Who Is Jain Ros? The Untold Story Behind Brave Girls' Hyeran

Jain Ros, formerly known as Hyeran, has emerged from the shadows of Brave Girls' original lineup to forge her own path as a solo artist. After stepping away from the K-pop scene in 2017 due to health concerns, she recently made her solo debut on October 8, 2024, with the single album "0 1 2 3" – marking a significant new chapter in her career.

During her time as one of the original Brave Girls members, Hyeran contributed significantly to the group's foundation before their eventual viral success with "Rollin'" in 2021. Standing at 170 cm tall and known for her fluent English skills, she was a distinctive presence in the Brave Girls profile until officially departing in 2019 when the K-pop group underwent reorganization. Notably, her resemblance to singer Son Dambi initially helped draw attention to both herself and the group.

Early Life and Background

Born as No Hyeran (노혜란) on April 9, 1993, the artist now known as Jain Ros began her journey far from the spotlight that would later define her career. Her story starts in the bustling port city of Incheon, South Korea, where she spent her formative years developing the talents that would eventually lead her to the K-pop industry.

Birthplace and education

Hyeran's roots in Incheon connect her to one of South Korea's major metropolitan areas, a city known for its rich cultural diversity and international influence. This urban upbringing might have contributed to her global outlook and eventual comfort with international audiences. While details about her family life remain private, her educational path provides insight into her artistic development.

For her formal education, Hyeran attended Hanlim Multi Art School, an institution renowned for nurturing young Korean talents in the performing arts. This prestigious school has produced numerous K-pop idols and entertainment figures over the years. At Hanlim, students receive specialized training in various artistic disciplines alongside their regular academic studies, providing an ideal environment for aspiring performers to develop their skills.

Standing at 169 cm tall, Hyeran possessed the physical presence that would later serve her well on stage as a member of Brave Girls. Her time at Hanlim likely helped shape both her artistic vision and professional discipline—qualities essential for anyone hoping to succeed in South Korea's competitive entertainment industry.

Pre-debut interests and talents

Beyond her formal education, Hyeran cultivated several impressive talents that set her apart from many aspiring idols. Most notably, she demonstrated significant musical ability outside of singing and dancing. She developed proficiency with both the cello and piano, instruments that require years of dedicated practice to master. This classical music background gave her a strong foundation in music theory and performance that would later enhance her capabilities as a Brave Girls member.

Among her personal interests, swimming ranked as one of her favorite activities. This athletic pursuit complemented her dance training and likely contributed to her stamina and physical conditioning—important attributes for the demanding performances expected of K-pop idols.

Perhaps one of her most valuable pre-debut skills was her ability to speak English. This linguistic capability would later distinguish her within the Brave Girls profile and enhance her ability to connect with international fans. While many K-pop idols study English intensively after debut, Hyeran already possessed this skill before entering the industry.

These combined talents—musical instruments, athletic interests, and language abilities—painted the picture of a well-rounded individual prepared for the multifaceted demands of K-pop stardom. Additionally, her diverse skill set likely contributed to her selection during the Brave Girls audition process, setting the stage for her eventual debut as part of the original lineup under Brave Entertainment.

Each of these formative experiences and personal attributes would ultimately shape Hyeran's artistic identity—first as a member of BBGirls and later in her transformation into solo artist Jain Ros.

Joining Brave Girls: The Beginning

The path to K-pop stardom began for Hyeran in late 2010 when Brave Brothers, the founder of Brave Entertainment, announced plans to debut a new girl group. This announcement set the wheels in motion for what would become one of the more enduring stories in K-pop—a group that would eventually experience both struggles and remarkable success.

How Hyeran was selected

In the competitive world of K-pop training and selection, Hyeran stood out with her combination of rap skills, dance ability, and multilingual talents. On March 17, 2011, Brave Entertainment officially announced Hyeran as the second member of Brave Girls. This announcement came during the final preparation phase as the company was building anticipation for their upcoming debut.

While specific details about her audition process remain private, Hyeran's selection likely stemmed from her impressive skill set. Her ability to play multiple instruments including cello and piano, coupled with her English language proficiency, made her a valuable asset for a group hoping to establish an international presence. Furthermore, at 169.8 cm tall, she had the physical presence that aligned with the industry's visual expectations.

The selection period moved quickly from announcement to debut, giving the trainees limited time to prepare as a cohesive unit before facing the public. Nevertheless, this accelerated timeline suggests Brave Entertainment's confidence in their newly formed team.

Her role in the original lineup

Hyeran debuted with Brave Girls on April 8, 2011, with their first single album "The Difference". As part of the original five-member lineup alongside Eunyoung, Seoah, Yejin, and Yoojin, she helped establish the group's initial identity and sound. Within this configuration, Hyeran took on crucial positions that shaped the group's performance style:

Main Rapper - Leading the rap segments that became a signature element of early Brave Girls tracks
Main Dancer - Showcasing choreography skills that helped define the group's performance style
Vocalist - Contributing to the group's harmonies and overall sound

Following their debut, Brave Girls quickly released their first mini-album "Back To Da Future" in June 2011, promoting the single "Easily". The group's reception proved promising—while not achieving immediate breakthrough success, they established a solid foundation in the highly competitive K-pop landscape.

Their debut year concluded with significant recognition as Brave Girls received nominations for Best New Female Artist at the Mnet Asian Music Awards (MAMA) and won Rookie Of The Year at the Korea Culture Entertainment Awards. These accolades validated the potential of the original lineup and Hyeran's contributions to their early success.

Throughout this initial period, Hyeran helped shape the BBGirls identity through her distinctive rap style and dance performances. Her fluency in English also positioned her as a potential bridge to international audiences—an increasingly important consideration for K-pop groups at that time. Despite coming from a smaller entertainment company, the original Brave Girls lineup established themselves as promising newcomers in the competitive K-pop scene.

Hyeran’s Role in Brave Girls

Within the original lineup of Brave Girls, Hyeran quickly established herself as a multifaceted performer whose talents helped shape the group's identity. As one of the five founding members, her contributions extended far beyond merely filling a position on stage.

Main rapper and dancer

Throughout her tenure with Brave Girls, Hyeran served as the group's main rapper, bringing a distinctive flow and delivery to their early discography. Her rap segments in tracks like "Do You Know" and "Easily" showcased her technical ability and charismatic delivery. Beyond her rapping prowess, she also held the position of main dancer, helping establish the group's performance style with her precise movements and stage awareness.

Hyeran's artistic versatility extended to her vocal contributions as well. Unlike many idol rappers who focus exclusively on rap sections, she demonstrated competence as a vocalist, allowing her to participate more fully in the group's overall sound. This multifaceted approach made her an essential component of BBGirls' musical identity during her active years.

Her fluency in English proved particularly valuable for Brave Girls, especially during international appearances and when recording English versions of their songs. This linguistic advantage positioned her as a potential bridge to global markets at a time when K-pop was beginning its international expansion.

Mentorship within the group

As one of the original members of Brave Girls, Hyeran naturally assumed a mentorship role as the group underwent multiple lineup changes. When new members joined following departures in 2013-2014, she represented continuity and institutional knowledge within the constantly evolving group.

Her seniority within Brave Girls became increasingly significant after the departure of fellow original members. By 2016, as the group prepared for their "High Heels" comeback with a substantially altered lineup, Hyeran remained as one of the few veterans who could guide newer members through the challenges of idol life.

Throughout lineup changes, Hyeran's steady presence provided stability during periods of transition. Her experience proved invaluable for integrating new members into the group's established dynamic while helping maintain Brave Girls' core identity despite personnel changes.

Stage presence and fan appeal

On stage, Hyeran commanded attention with her confident performance style and expressive delivery. Her background in dance and rap created a compelling stage presence that distinguished her within the group's performances. Standing at nearly 170 cm tall, her physical presence complemented her performance abilities.

Notably, during Brave Girls' early promotional period, Hyeran gained attention for her resemblance to established singer Son Dambi – a comparison that helped draw initial interest to both her and the group. This visual recognition factor contributed to her individual recognition among fans.

With fans, Hyeran cultivated a reputation for her approachable personality and genuine interactions. Her communication skills, particularly in English, allowed her to connect with international supporters in a more direct manner than many of her contemporaries. These authentic exchanges helped build a dedicated fanbase that would continue supporting her even after her departure from the group.

As her health began affecting her ability to perform, Hyeran's dedication remained evident through her determination to fulfill commitments whenever possible. This professional attitude, coupled with her talents, established her as a respected figure within the brave girls profile – setting foundations that would continue influencing the group even after her eventual departure in 2019.

Challenges and Hiatus

In early 2017, a significant announcement from Brave Entertainment marked a turning point in Hyeran's journey with Brave Girls. After years of contributing to the group's identity as both rapper and dancer, circumstances beyond her control would force her to step back from the spotlight.

Health issues and official hiatus

On January 13, 2017, Brave Entertainment released a statement that would permanently alter the Brave Girls lineup. The company announced that Hyeran would be taking an indefinite hiatus from all group activities due to health concerns. According to the official statement, "Due to a sudden worsening of Hyeran's health, we determined that it wouldn't be possible for her to promote with Brave Girls [at this time]."

The announcement emphasized that the decision came after careful consideration of Hyeran's wellbeing: "Putting our artist's health first, we decided after much discussion that Hyeran would be taking a temporary leave from the group." This prioritization of health over promotional activities reflected the serious nature of her condition, although specific details about her medical issues were not disclosed at the time.

Notably, Hyeran's hiatus announcement coincided with another significant personnel change - original member Yoojin's permanent departure from Brave Girls to focus on education and preparation for studying abroad. These simultaneous changes left the group with none of its founding members in active status.

In a revealing May 2025 video interview, Hyeran finally addressed the true nature of her departure, confirming that she had ultimately left Brave Girls "due to worsening health stemming from the conditions of working as an idol." This candid acknowledgment shed light on the often grueling reality behind K-pop's polished façade.

Emotional impact and public response

The sudden announcement of Hyeran's hiatus generated significant concern among the BBGirls fanbase. For loyal supporters who had followed the group since debut, her absence represented the loss of a final connection to the original lineup and a valued performer within the group dynamic.

Interestingly, attentive fans had noticed potential signs of changes within Brave Girls months before the official announcement. As early as November 2016, observers compiled evidence suggesting potential lineup changes. These indicators included:

Hyeran and Yoojin's absence from scheduled performances
Modifications to Brave Girls' choreography to accommodate five members instead of seven
Changes to the group's standard greetings
Removal of Brave Girls-related content from Hyeran's social media accounts
The pair's continued social media activity despite being reportedly "sick" for group events

Following the announcement, Brave Entertainment confirmed they would proceed with Brave Girls as a five-member group consisting of Minyoung, Eunji, Yuna, Yujeong, and Hayun. The company stated: "The five members are preparing for a new release in February or March, and from that point we will be actively promoting the group member's collective and solo activities."

Though initially framed as a "temporary leave," Hyeran's hiatus ultimately became permanent. The extended absence eventually concluded with her formal departure from Brave Girls and Brave Entertainment entirely, setting the stage for her later reinvention as solo artist Jain Ros.

For both Hyeran and the Brave Girls profile, this period represented a pivotal transition. The group would continue evolving through subsequent lineup changes and eventually achieve remarkable viral success with "Rollin'" in 2021 - long after Hyeran's departure - whereas she would forge an entirely new path outside the Brave Girls kpop identity that had defined her early career.

Life After Brave Girls

After her indefinite hiatus announcement in January 2017, Hyeran's relationship with Brave Entertainment underwent a significant transformation that eventually led to her complete departure from the company. What began as a health-related pause gradually evolved into a permanent separation from the Brave Girls identity she had helped establish.

Departure from Brave Entertainment

While initially framed as a temporary break, Hyeran's absence from Brave Girls activities became permanent over time. Though the exact timeline remains somewhat ambiguous in official statements, industry sources indicate her formal departure likely occurred around the time of the "Rollin'" release in March 2017. However, Brave Entertainment did not publicly confirm her departure until March 2019, approximately two years after she stopped participating in group activities.

This extended period between her initial hiatus and official departure announcement created confusion among fans. Many supporters continued hoping for her eventual return to the group, primarily because the company had specifically characterized her absence as "temporary" rather than permanent.

The confirmation finally came during an interview with Brave Brothers in March 2019, when the company acknowledged that both Hyeran and fellow member Hayun had officially left the group. This announcement coincided with Brave Girls' reorganization, setting the stage for what would become their unexpected viral resurgence with "Rollin'" in 2021 - long after Hyeran had moved on to new ventures.

Entrepreneurial ventures and internet broadcasting

Shortly after stepping away from Brave Girls, Hyeran demonstrated her entrepreneurial spirit by launching "Miraiki," her own accessory business. This creative venture quickly gained traction, with several celebrity connections helping promote the brand through their social media platforms. Miraiki even secured sponsorship opportunities with prominent K-pop groups, including Cosmic Girls and Girl's Day during their "I'll Be Yours" promotions.

Consequently, Hyeran established herself as a business owner while simultaneously exploring opportunities in internet broadcasting. This digital platform allowed her to connect directly with audiences without the constraints of the traditional idol industry structure. Through her broadcasts, she maintained a connection with fans while developing a more personal identity separate from her BBGirls persona.

Remarkably, Hyeran maintained relationships with several former Brave Girls members after her departure. Both Yejin (from the first generation lineup) and Hayun (from the second generation) appeared on Hyeran's internet broadcasts, demonstrating ongoing friendships beyond their shared professional experiences.

On March 4, 2021, Hyeran addressed Brave Girls' unexpected viral success during an Instagram Live session. She expressed sincere congratulations for their "Rollin'" reverse run phenomenon, noting that she had "always wanted the team to do well" and was "fortunate that it came true". Nevertheless, she explained she hadn't previously mentioned the group publicly because she "didn't want to be a nuisance" to an active team and needed to "forget the lingering attachments" to her former group.

This honest reflection revealed both her continued goodwill toward her former colleagues and her determination to forge her own path beyond the brave girls kpop identity that had defined her early career.

Reinvention as Jain Ros

After years away from the spotlight, the former Brave Girls rapper emerged with a new identity in 2021, quietly adopting the stage name "Jain Ros" as she prepared to reintroduce herself to the music world. This transformation marked more than just a name change—it represented a complete artistic rebirth separate from her previous identity as part of the brave girls kpop universe.

Why she changed her stage name

The transition from Hyeran to Jain Ros began behind the scenes in 2021, yet remained largely unknown to the public until January 17, 2024, when she officially announced she would be proceeding with her solo career under this new moniker. The announcement coincided with confirmation that her long-anticipated solo debut was still in progress, with a target release window between February and April of that year.

In interviews, the former BBGirls member has described her name change as part of a broader journey toward creative independence and personal healing. As she explained in a Gold Street interview, stepping away from idol life allowed her to find her own voice as a solo artist. The new name symbolized a clean break from her past while honoring her evolution as both a person and musician.

Unlike her time in Brave Girls, where her identity was intrinsically tied to the group's concept and direction, the Jain Ros persona gave her complete control over her artistic expression and public image. This reinvention essentially allowed her to reset public expectations and introduce herself on her own terms, without the shadow of her former group looming over her creative decisions.

Creative direction and musical style

As Jain Ros, the former brave girls member embraced a significantly different musical approach than the high-energy dance tracks that defined her previous career. Her debut single album "0 1 2 3," released on October 8, 2024, showcased a more introspective and healing-focused sound.

Most importantly, Jain Ros took an active role in music production—something rarely possible within the brave girls profile structure. She personally composed the first two tracks of her debut album and contributed to both lyrics and composition of the title song. These tracks—"0 - PLAZMARIA [963Hz]" and "639Hz"—were crafted with synth sounds and ambient music focused on self-discovery and healing, using frequencies designed to resonate with the body.

The message behind her new musical direction spoke volumes about her personal journey. As she explained, her debut album addressed "the moment when you take your first steps into the society of your dreams, experiencing new situations for the first time". This theme of new beginnings perfectly mirrored her own transformation from Hyeran to Jain Ros.

To fund her independent vision, she organized a crowdfunding campaign through Tumblbug for her debut single album in April 2024. This grassroots approach demonstrated both her entrepreneurial spirit and the supportive fanbase she maintained despite years away from the industry.

Solo Debut and Music Projects

October 2024 marked a pivotal moment in Hyeran's musical journey as she officially debuted as a solo artist under her new identity. The transformation from Brave Girls rapper to independent soloist represented years of behind-the-scenes preparation and personal growth.

Release of '0 1 2 3'

After years of development, Jain Ros officially released her debut single album "0 1 2 3" on October 8, 2024. The project had been in preparation since 2019, with early teasers appearing in December 2021. The album featured a healing-focused concept, with Jain Ros explaining it addressed "the moment when you take your first steps into the society of your dreams".

The album showcased her artistic evolution, featuring tracks "0 - PLAZMARIA [963Hz]" and "639Hz" that utilized specific frequencies designed for physical and emotional healing. Most remarkably, she personally composed these tracks and contributed to both lyrics and composition of the title song "PLAY WITH Ü". The album even featured a collaboration with Yoojin, her former Brave Girls bandmate.

Crowdfunding and fan support

Prior to her official debut, Jain Ros took an unconventional approach to funding her project. In April 2024, she announced a crowdfunding campaign through Tumblbug to support her debut single album. This grassroots strategy demonstrated both her entrepreneurial spirit and the loyal fanbase she maintained despite years away from the spotlight.

The successful campaign allowed her to release the album first digitally on streaming platforms before creating a physical version. This phased approach maximized her resources while building momentum for her solo career.

Follow-up single 'Log In'

Building on her debut momentum, Jain Ros released a physical KiT version of "0 1 2 3" on November 29, 2024, which included an exclusive new track titled "Log In". Subsequently, on February 28, 2025, she released a music video for this previously exclusive song.

Through direct fan interaction, she revealed that "Log In" would be included in her upcoming mini album. The track was ultimately made available on digital platforms on May 25, 2025, expanding her growing discography as she continues establishing her identity beyond her BBGirls roots.

Public Image and Personal Traits

Beyond her musical talents, Hyeran's distinctive visual appeal and personality have played crucial roles in shaping her identity both within Brave Girls and as solo artist Jain Ros.

Ulzzang background and visual appeal

Fundamentally, Hyeran's visual presence contributed significantly to her early recognition in the industry. As a model in addition to her performing career, she developed a distinctive aesthetic that complemented her musical identity. Her creative eye eventually extended into professional territory as she became founder and lead creative artist at YelloYellow Studio in Seoul, where she creates branded videos and social media content for music, fashion, beauty, and lifestyle products.

In effect, this visual sensibility has influenced her artistic direction throughout her evolution from Brave Girls member to independent artist. Her approach to styling and visual presentation remains a key component of her Jain Ros persona, with her creative background informing the aesthetic choices in her music videos and promotional materials.

Personality, hobbies, and fun facts

Born under the Aries zodiac sign, Hyeran displays many traits associated with this fire sign—determination, confidence, and creative passion. Her educational background at Hanlim Multi Art School provided a foundation for her artistic development and creative expression. Moreover, her ability to speak both Korean and English reflects her global outlook and communication skills.

In general, Hyeran describes music as something that "keeps me in the moment"—a philosophy that seems to guide her approach to artistic expression. This mindset appears to have sustained her through career transitions and personal challenges, serving as an anchor during periods of change.

Relationship with former members

Above all, Hyeran has maintained connections with several former BBGirls colleagues despite her departure from the group. Most notably, she collaborated with Yoojin, another original brave girls profile member, on the title track of her debut solo album "0 1 2 3." This continued professional relationship suggests enduring personal bonds beyond their shared history.

As well as professional collaborations, she has maintained personal friendships with some former groupmates. Her willingness to incorporate these connections into her current work as Jain Ros demonstrates both loyalty to her roots and a healthy integration of her past experiences into her evolving identity as an artist.
