PRIMROSE Kpop: The Secret Story Behind Each Member (2025)

PRIMROSE kpop stands out as one of the industry's most fascinating evolution stories, transforming from an original duo into a dynamic four-member group. Behind their polished performances and synchronized choreography lies a complex journey filled with departures, new additions, and personal growth.

The current PRIMROSE members represent a carefully assembled team of talented individuals with diverse backgrounds. Specifically, the group includes former idols from bugAboo and HOT ISSUE alongside original members who weathered the group's transformations. Despite these changes, PRIMROSE's profile continues to evolve while maintaining their unique musical identity. Furthermore, each member of this kpop group contributes distinct vocals, performance styles, and personalities that have captivated an ever-growing fanbase.

Rainie: From bugAboo to PRIMROSE

Rainie represents one of PRIMROSE's most intriguing comeback stories. The Taiwanese vocalist arrived at the group with a wealth of experience and a devoted fanbase already intact, bringing fresh energy to the evolving ensemble.

Early life and training journey

Born Chu Ch'ing Yü on November 16, 2000, in Taipei, Taiwan, Rainie's performance career began long before her K-pop debut. Initially, she worked as a child actress, appearing in films such as "The M Riders: Finding Pangu" as the character Dandan. Her journey in the Korean entertainment industry officially started on March 7, 2019, when she joined A Team Entertainment as a trainee.

During this early period, Rainie (then using the stage name Rainieju) was introduced as a potential member of a pre-debut girl group called ISE through a performance at Miss Malaysia's 2019 pageant. Her training culminated in her official debut with bugAboo (formerly ISE) on October 25, 2021, after being revealed as the group's third member.

Throughout her training, Rainie developed impressive skills in both singing and dancing. She mentions being most comfortable dancing to GFriend's "Glass Bead" and singing IU's "Dear Name". Additionally, she completed her education at Janggyeong High School.

Why she left bugAboo

Contrary to what some might assume, Rainie didn't choose to leave her previous group. On December 8, 2022, A Team Entertainment announced bugAboo's official disbandment after deciding to terminate the group's contract and future activities. This came only 14 months after the group's debut, cutting short their promising career.

The sudden disbandment left talented members like Rainie without a platform to showcase their abilities. However, this unexpected career disruption ultimately created the opportunity for her to join PRIMROSE in the following year.

Her role and impact in PRIMROSE

On May 16, 2023, A.O Entertainment announced that Rainie would be joining PRIMROSE. She became the third member of the restructured group, following Nahyun (formerly of HOT ISSUE) who had also recently joined.

Rainie's addition to PRIMROSE brought excitement among fans of both groups. Comments on social media showed enthusiasm with fans noting: "I'm so happy for Rainie!! She was my bias in bugAboo so I was sad to see her go but this is so exciting!". Another fan remarked: "As someone who was a fan of both bugaboo and hot issue, this makes me happy to hear. Glad they're getting a second chance".

Her artistic contributions are beginning to shape the group's direction. In an interview, Rainie expressed interest in exploring new concepts: "I want to do a killer concept! I also want to try a lot of acting in the music video!".

Unique traits and fan-favorite moments

Rainie possesses several distinctive characteristics that endear her to fans:

She's known for her dimples, which she considers her charming point
Her nickname "Rainism" comes from Rain's song of the same name
She describes herself as a "#pink_princess" and someone good at making diverse facial expressions

Moreover, Rainie has notable musical influences. She's a dedicated fan of Girls' Generation, mentioning that their album "The Boys" was the first she ever purchased for herself. When asked about potential collaborations, she enthusiastically responded: "I really like the members of Girls' Generation, so I would like to work with them if I get the chance!".

Her MBTI personality type is ENFP, reflecting her outgoing nature. When reflecting on her most precious memories with PRIMROSE members, she shared: "I think the memories we made while eating and talking all night are the most precious!".

As a result of these qualities and her previous experience, Rainie has quickly established herself as an integral part of PRIMROSE's identity, bringing both technical skill and vibrant personality to the reconfigured group.

Nahyun: The Vocal Powerhouse

Nahyun brings exceptional vocal talent to PRIMROSE kpop, establishing herself as the group's main vocalist with a distinctive husky voice that sets her apart in the competitive K-pop industry.

Her HOT ISSUE days

Nahyun's idol journey began long before PRIMROSE. Notably, she debuted with HOT ISSUE on April 28, 2021, after being introduced as the group's first member on March 22 that same year. Throughout her time with HOT ISSUE, she earned recognition for her striking visuals and unique vocal color, often described as having a "rhythmic and husky voice".

Unfortunately, HOT ISSUE's career was unexpectedly cut short when the group disbanded on April 22, 2022, just six days before their first anniversary. The decision came after lengthy discussions between the members and S2 Entertainment about the group's future direction. Nevertheless, Nahyun's time with HOT ISSUE showcased her leadership abilities and vocal talents, laying groundwork for her future endeavors.

Joining PRIMROSE and adapting

Following HOT ISSUE's disbandment, Nahyun was officially announced as a new member of PRIMROSE on May 3, 2023. This announcement came at a pivotal moment for PRIMROSE kpop, as original member Yeum had recently withdrawn due to personal circumstances and health problems.

Nahyun's addition brought renewed energy to the group. As she joined existing member Ruby, fans of both HOT ISSUE and PRIMROSE expressed excitement about her new beginning. The transition represented a second chance for Nahyun to showcase her talents after her previous group's early dissolution.

Her vocal style and strengths

What truly distinguishes Nahyun within the PRIMROSE members lineup is her distinctive approach to music. In her own words: "I tend to listen to the lyrics more importantly than the melody, so I try to deliver the lyrics better. I think that's one of the strengths and efforts I put in". This emphasis on lyrical delivery enhances her performances and connects deeply with listeners.

Moreover, Nahyun possesses versatility as a performer. She creates "music of various genres in her style", complemented by her visual presence and model-like physique. When discussing her experience with PRIMROSE's energetic concepts, she revealed: "I found that I can enjoy performing even more when working on an exciting song. Thanks to the energy of the song, I get more energy from the performance".

Personal hobbies and personality

Beyond her professional life, Nahyun has diverse interests that shape her personality. Her hobbies include:

Jogging, reading, and boxing for physical activity
Songwriting and cooking as creative outlets
Taking solitary walks during breaks

Born in Changwon, South Korea on January 25, 2002, Nahyun identifies as an INFJ personality type. This introspective personality aligns with her thoughtful approach to music and performance. She attended Seonjeong High School and previously took vocal classes at High Up Vocal Academy.

Concerning musical preferences, Nahyun gravitates toward R&B and ballad genres. Interestingly, she mentions EXID's Hani as her role model, suggesting an admiration for versatile performers who maintain longevity in the industry.

With approximately 5-6 years of training experience at prominent companies including Cube Entertainment (2016) and Source Music (2017), Nahyun brings both technical skill and artistic vision to the PRIMROSE kpop profile.

Ruby: The Original Spark

As one of the founding pillars of PRIMROSE kpop, Ruby remains the enduring heartbeat of the group since its inception, carrying its original vision through every transformation the ensemble has undergone.

Being part of the original duo

Ruby (birth name: Heo Ji-won) was introduced as the first member of the PRIMROSE duo on November 10, 2022. Alongside original member Yeum, she helped establish the group's foundation before their official debut on January 13, 2023, with the mini album "Red Moon". This debut came after approximately three years of training, demonstrating her dedication to perfecting her craft.

Prior to joining PRIMROSE, Ruby had already accumulated experience in the industry as a former member of the pre-debut girl group Elado in 2017. This early exposure undoubtedly contributed to her polished performance style and stage presence that would later benefit PRIMROSE kpop.

Her rap and dance skills

Within the PRIMROSE profile, Ruby holds the positions of Main Rapper and Main Dancer, roles that showcase her diverse talents. Though primarily recognized for her rapping abilities, she possesses what industry insiders describe as a "bright and lively voice" with "splendid rapping skills".

Her dance background runs deep—Ruby has revealed that she has enjoyed dancing since childhood. Critics and fans alike acknowledge her for demonstrating "smooth and clean dance lines". Yet perhaps what makes her particularly valuable to PRIMROSE kpop members is her versatility; she freely performs various dance genres, allowing the group to explore different concepts.

Essentially, despite her rapper designation, Ruby has demonstrated outstanding vocal abilities through covers such as Rosé's "GONE" and George's "Boat". This versatility allows her to contribute to multiple aspects of the group's performances.

Creative side: photography and gaming

Beyond her on-stage persona, Ruby nurtures several creative hobbies that reflect her artistic sensibilities:

Photography and photo editing rank among her favorite pastimes
Gaming, particularly Mobile KartRider, which she enjoys playing until 2:00 AM
Collecting perfumes, reflecting her appreciation for sensory experiences
Driving, which provides her with independence and mobility

These interests contribute to her creative vision within PRIMROSE. In interviews, she's expressed particular enthusiasm for the song "Steal Heart," specifically admiring the lyric, "The most dramatic scene you've ever seen is me"—perhaps reflecting her own artistic sensibilities.

How she shaped the group's identity

Ruby's influence on PRIMROSE kpop's identity cannot be overstated. She selected her stage name with specific intent—she wanted to shine "like a jewel", a philosophy that has seemingly guided the group's bright, eye-catching concepts.

In the group dynamic, Ruby serves as the "mood maker", bringing energy and positivity. When describing her role in PRIMROSE's activities, she stated: "I took on the role of the conductor, figuring out the path in my mind and communicating all the details". This leadership quality has been vital through the group's transitions.

Physically, Ruby embodies what some call the "idol rabbit image" with her oval face and round eyes, creating a recognizable visual identity for the group. She considers her smile her greatest strength, noting: "I think I'm most attractive when I smile. That's my strength!".

Although compact in stature at 156 cm (5'1"), her impact on PRIMROSE kpop group has been immeasurable. Through lineup changes and concept evolutions, Ruby has remained the consistent thread connecting the group's past to its promising future.

Hayun: The Youngest with a Vision

Unlike her bandmates, Hayun stands out in the PRIMROSE kpop lineup as the only member without previous experience in another group. This fresh perspective brings a unique energy to the ensemble's dynamic.

Her late addition to the group

Hayun (birth name: Ha Seyun) was revealed as the final new member of PRIMROSE on June 22, 2023. In contrast to the other PRIMROSE members who transitioned from disbanded groups, Hayun joined as a complete rookie. Subsequently, she completed the revamped four-member configuration, representing new blood in a group already undergoing significant transformation.

Born on November 20, 2003, in Daegu, South Korea, Hayun entered the industry at just 19 years old. Her educational background includes attending Seoul Performing Arts High School, providing her with formal training in the performing arts before her debut.

Musical talents and favorite genres

Regarding musical abilities, Hayun possesses a remarkably distinctive husky voice that captivates listeners. Her vocal prowess became evident during live performances, especially her solo rendition of Karina Pasian's "Slow Motion," which critics described as a "vocal masterpiece" highlighting her "smooth, emotive tone".

Beyond singing, Hayun demonstrates instrumental versatility. She can play both the keyboard and piano, skills that enhance her musical contributions to the group. Concerning personal taste, she gravitates toward R&B as her favorite genre, with EXO's Baekhyun serving as her musical role model.

Her role as the maknae

As the youngest member of PRIMROSE kpop profile, Hayun naturally assumes the position of maknae (youngest member). Hence, she brings what fans affectionately describe as "trendy stage control", helping the group maintain relevance with younger audiences.

Within the group dynamic, Hayun holds the positions of Lead Rapper and Sub Vocalist, complementing her maknae status with significant performance responsibilities. Her MBTI personality type is INTJ, suggesting an analytical and strategic mindset beneath her youthful exterior.

How she connects with fans

Hayun engages with fans through thoughtful interactions and memorable performances. At concerts, she creates intimate moments through her emotional vocal delivery, as witnessed during the "With Love, PRIMROSE" concert. Between songs, she participates enthusiastically in interactive segments with audiences, including attempting local language challenges like Finnish tongue twisters.

Her aspirations reveal much about her character. In interviews, Hayun has expressed ambitious goals:

"I have big goals as a solo artist like Taeyeon"
"My dream as PRIMROSE is to make our group name known and to be number one someday"
"When our group becomes successful, I want to sing a song I wrote!"

These statements demonstrate both her individual ambition and commitment to the group's success. Furthermore, during rare free moments, she enjoys simple pleasures—eating delicious food and watching shows on Netflix and TVing, revealing the everyday person behind the idol image.

Yeum: The Voice That Started It All

Yeum's departure from PRIMROSE kpop created a pivotal moment in the group's evolution, but her contributions as a founding member remain an essential part of their story.

Her time in the original duo

Originally introduced as the second member of the PRIMROSE duo on November 11, 2022, Yeum (birth name: Jeong Myong-woo) quickly established herself as a vocal cornerstone of the nascent group. Together with Ruby, she participated in the official debut of PRIMROSE on January 13, 2023, with the mini album "RED MOON". Throughout this foundational period, Yeum served as the Main Vocalist, bringing her distinctive vocal color to the group's initial identity.

Before joining PRIMROSE kpop group, Yeum was a member of Azer Blossom under her birth name. Her extensive preparation for debut included three years of training and education at Fuze Practical Music Academy Daehangno Branch. The name "Yeum" itself carries significance—it represents her desire to be recognized for her vocal talent, literally meaning "talent in sound".

Why she left PRIMROSE

Regrettably, Yeum's time with PRIMROSE kpop members proved brief. On March 23, 2023, AO Entertainment announced her departure, citing both personal circumstances and health problems as the primary reasons. This announcement came merely two months after the group's debut, transforming what was once a duo into Ruby's solo project until new members could be added.

After leaving PRIMROSE profile, she completely rebranded herself—changing her Instagram username from prim_yeum1 to _thingvv0.0 and reverting to her birth name Myongwoo. This dramatic shift suggested deeper issues beneath the official "health reasons" explanation.

Her musical legacy

Musically, Yeum was known for her strength in the R&B genre. Her vocal capabilities were exceptional, featuring a unique combination of husky low notes paired with "light and refreshing" high notes. This versatility allowed her to contribute significantly to PRIMROSE's debut sound.

Beyond performing, Yeum possessed profound passion for songwriting, even maintaining an entire book filled with her original lyrics. Her creative vision extended to potential future collaborations—she expressed desire to work with Paul Kim and explore acting opportunities.

Fan memories and tributes

Fans still fondly recall Yeum's memorable traits:

Her collection of nicknames including Pingu, Yem, and Maemwoo
Her ENFP personality that brought energy to the group
Her unique ability to imitate Doraemon's voice
Her meaningful arm tattoo reading "지금부터 환상의 쇼가 펼쳐집니다" ("From now, a fantastic show will be held")

Even after her departure, fans continue to follow her personal Instagram (@thingvv0.0), where she occasionally posts updates. Indeed, her status as a founding member of PRIMROSE kpop ensures her lasting place in the group's history, regardless of her brief tenure.

How PRIMROSE Members Complement Each Other

The magic of PRIMROSE kpop emerges most clearly through the members' complementary skills and personalities. Beyond their individual talents, it's their collective harmony that creates the group's distinctive appeal in today's competitive industry.

Vocal and performance balance

Vocally, the PRIMROSE members form a perfect ensemble where each voice fills a specific niche. Nahyun serves as the main vocalist with her husky, rhythmic tone that anchors the group's sound. In her own words, she focuses on "delivering the lyrics better" rather than merely following melodies, creating emotional depth in performances. Meanwhile, Rainie contributes as lead vocalist with exceptional facial expressions that enhance her delivery.

The performance dynamic achieves balance through Ruby's leadership as main dancer and rapper, bringing "bright and bouncy vocal tone" alongside "splendid rapping skills" to the group. Correspondingly, Hayun's distinctive husky voice adds another layer of vocal texture. This deliberate distribution of talents ensures PRIMROSE kpop profile maintains versatility across different musical concepts.

MBTI dynamics and group chemistry

Ruby (ISFJ) offers practical reliability, coupled with Hayun (INTJ) providing analytical perspective. This quartet of personalities creates natural chemistry, resembling what one MBTI expert described as "explosive" interaction between intuitive types.

According to personality type research, this blend of MBTI types produces both creative tension and mutual support. As one observer noted about similar combinations: "There is always initial insane chemistry". For PRIMROSE kpop group, these personality differences don't create conflict but rather foster complementary dynamics where each member's strengths offset others' limitations.

Stage presence and off-stage roles

On stage, PRIMROSE members exhibit different but complementary presence styles. True stage presence, according to performance experts, comes from "literally being present" mentally and achieving immersion in the performance. Each PRIMROSE kpop member contributes uniquely - Ruby maintains her role as "mood maker", while Nahyun stays "calm" as her strength.

Off-stage, their diverse interests further strengthen group cohesion. Ruby's photography skills help document their journey, whereas Hayun's keyboard abilities add musical dimension. In essence, what makes PRIMROSE kpop members special is how they function as a complete unit rather than competing individuals. This collaboration extends beyond performances into their creative process, where according to one inside source, performing together creates a "channel through which emotion just flows through, out through me into the audience".

The Evolution of PRIMROSE’s Image

PRIMROSE kpop's visual identity underwent remarkable transformation throughout their journey, shifting from an intimate duo concept to a multifaceted four-member ensemble with expanded artistic possibilities.

From duo to 4-member group

The evolution of PRIMROSE began with the original pairing of Ruby and Yeum in November 2022, creating an intimate musical dynamic that defined their January 2023 debut. After Yeum's unexpected departure in March 2023, Ruby briefly continued solo until the group gradually rebuilt. Firstly, Nahyun joined in May 2023, bringing her HOT ISSUE experience and distinctive vocal color. Shortly afterward, Rainie arrived with her bugAboo background, adding Taiwanese representation and performance versatility. Finally, rookie Hayun completed the quartet in June 2023, introducing fresh perspective without prior group experience.

This transformation from duo to quartet fundamentally altered PRIMROSE kpop profile, enabling more complex choreography, diversified vocal arrangements, and enhanced visual storytelling. Certainly, each lineup change represented not merely a numerical adjustment but a complete reimagining of the group's potential and direction.

Concept changes across albums

Upon reconstruction into a quartet, their stylistic approach evolved accordingly. The expanded lineup allowed for greater conceptual range—moving from the intimate, focused performances of the duo era toward more dynamic, visually intricate presentations.

Throughout their releases, PRIMROSE members explored various aesthetic directions while maintaining core elements that defined their sound. Ruby, as the consistent thread connecting all eras, ensured continuity in the group's identity even as their concepts matured and diversified with each release.

How each member influenced the group's style

Every PRIMROSE kpop profile now reflects unique stylistic contributions from each member. Ruby's founding vision for shining "like a jewel" established their bright, eye-catching aesthetic foundation. Simultaneously, Nahyun introduced sophisticated vocal approaches with her emphasis on lyrical delivery over melody. Rainie brought her acting background and expressive facial performance style, thereby expanding the group's emotional range.

As the final addition, Hayun completed the PRIMROSE kpop members' visual identity with her youthful perspective and "trendy stage control," keeping their appeal fresh for younger audiences.
