5 Former SECRET NUMBER Members: Where Are They Now in 2025?
SECRET NUMBER shocked the K-pop world when four of its members departed within just two days in April 2025. Léa officially left the group on April 3, 2025, after choosing not to renew her contract with Vine Entertainment. Meanwhile, Jinny, Dita, and Minji followed suit the very next day, announcing their departures on April 4, 2025.
The mass exodus came after a relatively short run for the K-pop group, which originally debuted on May 19, 2020, with their single album "Who Dis?". However, SECRET NUMBER had already experienced member changes previously when Denise announced her departure on February 5, 2022, though some sources indicate she officially left on February 1, 2022. Notably, the group's debut itself faced challenges, as they were originally scheduled to debut on March 26, 2020, but had to postpone due to the COVID-19 pandemic.
For fans wondering what happened to these former members of SECRET NUMBER, this article explores where each artist has landed after their time in the spotlight. From solo music careers to modeling contracts and acting projects, these seven talents have taken diverse paths following their SECRET NUMBER journey.
Denise
Denise Kim made history as the second revealed member of SECRET NUMBER on January 3, 2020, bringing her powerful vocals to the K-pop scene. Before joining the group, the Korean-American singer participated in the reality show K-pop Star 5 and trained with YG Entertainment for two years starting in May 2016. She eventually left YG and found her way to Vine Entertainment, where she became an integral part of SECRET NUMBER's debut on May 19, 2020, with their first single "Who Dis?".
Denise's role in SECRET NUMBER
As the main vocalist of SECRET NUMBER, Denise brought distinctive power and range to the group's sound. Her unique vocal color helped establish the group's musical identity during their first year of promotions. According to fan comments, "Denise vocals are the only one making Secret Number songs interesting", highlighting her significance to the group's musical appeal. She participated in the group's first two releases: their debut single "Who Dis?" and their November 2020 comeback "Got That Boom".
Why Denise left SECRET NUMBER
The first signs of trouble appeared on September 30, 2021, when Vine Entertainment announced that Denise would not participate in the group's upcoming album promotions due to "contract issues". She was notably absent from the October 2021 comeback "Fire Saturday," which featured two newly added members instead.
On February 5, 2022, Denise confirmed her departure through an Instagram post, stating: "As of February 1, 2022, my contract with Vine Entertainment has concluded". In her heartfelt message, she expressed gratitude toward her former members, whom she considered "sisters," and asked fans to continue supporting SECRET NUMBER despite her departure.
Several factors reportedly contributed to her exit. According to fan speculation, the group was "heading towards a more sexy and mature concept, which she didn't feel comfortable doing". Additionally, she was allegedly "sidelined" from her main vocalist position. Her aspirations as a composer and producer also faced roadblocks as she claimed she was denied opportunities to write for the group.
What Denise is doing now in 2025
Since leaving SECRET NUMBER, Denise has established herself as a multifaceted artist. In 2025, she successfully balances several professional pursuits:
Pursuing a music business degree (since 2023)
Songwriting for other artists (including boy group OX:N's "Suit & Tie")
Creating content online
Running her own business as an entrepreneur
In a recent interview, Denise reflected on her growth: "I think I've finally reached a point where I'm able to balance the different areas of my life, instead of feeling like I'm juggling them. I have a better sense of structure now". This newfound stability has allowed her to focus more on her creative endeavors and future music releases.
Denise's solo music and projects
After departing from SECRET NUMBER, Denise embraced independence by releasing her first EP titled "Me Before You" on December 29, 2022. Rather than considering it an official debut, she described the project as "more of a passion project" that represented her transition from idol to independent artist.
Since then, she has steadily built her discography with digital singles:
"Darling" (2023)
"Dopamine" (2024)
"Dance With Me!" (July 24, 2025)
Her latest single "Dance With Me!" marks a significant artistic evolution, embracing a more upbeat synth-pop sound than her previous releases. About this shift, Denise commented: "I never thought I would release something as upbeat and bright as 'dance with me!', but I'm excited to see the reaction of the listeners... I really want 'dance with me!' to showcase a different side of my artistry".
Looking forward, Denise has explicitly confirmed plans for more music, stating: "I do want to release more music... I have plans to make more music and actually release it this time". She describes 2024-2025 as a "turning point" in both her artistry and personal life, suggesting this period represents a new chapter in her career trajectory as she continues to evolve as an independent artist with creative control over her musical direction.
Léa
Japanese performer Ogawa Mizuki, better known as Léa, brought significant experience to SECRET NUMBER prior to joining the K-pop group. Originally debuting in the industry between 2011 and 2014 as a member of girl group Skarf under the stage name Hana, Léa later reinvented herself when she became part of SECRET NUMBER.
Léa's role in SECRET NUMBER
On February 27, 2020, Vine Entertainment revealed Léa as the fifth and final member of SECRET NUMBER. While preparing for their scheduled March 26, 2020 debut, the group faced an unexpected setback as the COVID-19 pandemic forced a postponement. Subsequently, SECRET NUMBER officially debuted on May 19, 2020, with their first single album "Who Dis?".
As the oldest member, Léa served as the group's leader, bringing stability and experience to the rookie ensemble. Her previous industry experience proved valuable for the multinational group as they navigated their early career. Throughout her tenure with SECRET NUMBER, Léa participated in all the group's releases, including their September 2024 first solo concert titled "Passworld" held in Jakarta, Indonesia.
Why Léa left SECRET NUMBER
After nearly five years with the group, Léa's exclusive contract with Vine Entertainment expired on April 2, 2025. The company officially announced her departure the following day, stating: "The exclusive contract period of Léa, who has showcased her shining talents as a member of SECRET NUMBER, has ended as of April 2, 2025".
Unlike situations involving contract disputes, Léa's departure appeared amicable, with Vine Entertainment expressing gratitude for her contributions: "First and foremost, we would like to express our gratitude to Léa for her hard work and dedication to the fans". The agency furthermore affirmed continued support for her future endeavors despite the end of her activities with SECRET NUMBER.
Her exit marked a significant turning point for the group, essentially triggering a series of changes. Shortly after Léa's departure announcement, Vine Entertainment acknowledged that discussions regarding the group's future activities and contract extensions had been taking place, which temporarily delayed their promotional schedule.
Léa's modeling and entertainment career
Following her departure from SECRET NUMBER, Léa quickly established her next career move. On June 4, 2025, she signed an exclusive contract with SNP Entertainment, where she reverted to using her birth name, Mizuki, for her professional activities. Her new agency announced plans to support her primarily in modeling and acting endeavors.
By August 2025, Léa had already begun building her portfolio as a model under SNP Entertainment. While still early in this career transition, her experience in the entertainment industry coupled with her visual appeal positioned her well for success in modeling. Her background as a K-pop idol provided her with camera experience, stage presence, and public recognition that enhanced her modeling potential.
Léa's social media and fanbase
Throughout her transition from idol to model, Léa maintained a connection with her fanbase through social media. While specific follower counts remain unavailable, her departure from SECRET NUMBER prompted an outpouring of support from fans who had followed her journey since 2020.
When Vine Entertainment announced her departure, they specifically requested: "We kindly ask the fans to also continue their unwavering support and encouragement for her", recognizing the strong connection Léa had built with the group's followers.
Despite moving to a different career path, Léa's established presence in the K-pop industry allowed her to retain much of her fanbase while potentially attracting new followers interested in her modeling work. Although this career shift represented a significant change, it demonstrated her versatility and determination to remain in the entertainment industry, albeit in a different capacity than before.
Dita
Anak Agung Ayu Puspa Aditya Karang, known professionally as Dita, made history as the first Indonesian female to debut in the K-pop industry when she joined SECRET NUMBER. Her groundbreaking entry into the Korean music scene opened doors for Southeast Asian representation in K-pop and established her as a pioneer for aspiring Indonesian idols.
Dita's role in SECRET NUMBER
Initially revealed as the fourth member of SECRET NUMBER on February 4, 2020, Dita served as the group's main dancer and sub-vocalist. Her background in dance was substantial—she had studied at the American Musical and Dramatic Academy's dance theater program and was previously associated with the renowned 1Million Dance Studio.
Her dance expertise was immediately recognized, with Vine Entertainment appointing her as the group's main dancer. Moreover, Jason Park, VINE Entertainment's music business division director, noted that Dita "has her own style, which greatly contributes to the group's songs". Throughout her time with SECRET NUMBER, Dita participated in the group's activities from their May 19, 2020 debut with "Who Dis?" until early 2025.
Why Dita left SECRET NUMBER
After nearly five years with the group, Dita announced her departure from SECRET NUMBER on April 4, 2025, through a joint statement with members Jinny and Minji. The trio revealed that their "contract with Vine Entertainment has been officially terminated, and therefore, official activities as SECRET NUMBER have now come to an end".
In their collective statement, they explained: "We've always gave our very best, but despite numerous discussions, we ultimately came to the conclusion that under the current situation, it would be extremely difficult for us to move forward". This announcement came just one day after Léa's departure was confirmed by Vine Entertainment.
Dita's ambassador roles and public appearances

On October 5, 2020, she was announced as the brand ambassador for global cosmetic brand Nacific Indonesia

These roles demonstrated her expanding influence outside of music and her ability to bridge cultural connections between South Korea and Indonesia.
Dita's influence in Indonesia
Undoubtedly, Dita's presence in K-pop resonated strongly with Indonesian fans. As the first female Indonesian idol in a K-pop group, she fostered a sense of pride and representation for her home country. Her journey from practicing K-pop dance covers in Yogyakarta to debuting on the global stage inspired many young Indonesians.
"It still feels surreal! The amount of love that I've received from Indonesian fans is crazy," Dita once shared about her reception in Indonesia. Even as she built her career in South Korea, she maintained her connection to her roots, stating: "South Korea is the right place for me to develop myself and I really enjoy working here... But Indonesia is, and always will be, my home".
Her advice to aspiring Indonesian K-pop idols reflected her pioneering spirit: "Just be true to yourself; if you find yourself really wanting to do it, it's possible. Everything is possible as long as you never give up". Through her achievements, Dita created a tangible path for other Southeast Asian talents to enter the K-pop industry.
Jinny
Jinny Park brings a compelling backstory to her SECRET NUMBER journey, having trained alongside future members of BLACKPINK at YG Entertainment from 2013 to 2017. Remarkably, she was part of YG's pre-debut girl group project known as "Pink Punk," which ultimately evolved into BLACKPINK without her inclusion. After leaving YG, she participated in the survival show Produce 48, where she placed 69th before finding her way to VINE Entertainment.
Jinny's role in SECRET NUMBER
As a core member of SECRET NUMBER from their debut in May 2020, Jinny showcased her talents primarily as a rapper and vocalist. Throughout her tenure, she participated in all the group's releases until early 2025. Despite her talents, Jinny later revealed she felt constrained within the group, describing herself as "a ziplock bag – transparent, so that people can watch me perform, but sealed, so that the contents inside the bag won't ever leak or fall out". She further explained: "I believe that I wasn't given the chance to reveal myself and to showcase my true style in music, due to many different factors and reasons".
Why Jinny left SECRET NUMBER
On April 4, 2025, just one day after Léa's departure announcement, Jinny released a joint statement with Dita and Minji declaring their exit from VINE Entertainment. In the heartfelt message, the trio explained that "despite numerous discussions, we ultimately came to a conclusion that under the current situation, it would be extremely difficult for us to move forward". This marked the official end of their contract with VINE Entertainment and consequently concluded their activities as SECRET NUMBER members.
The emotional weight of this departure was significant for both members and fans. In their farewell message, they expressed how they had "always gave [their] very best" throughout their time together. For many followers who had supported the group since 2020, this announcement represented the end of an era.
Jinny's solo debut and music plans
Wasting no time in pursuing her artistic vision, Jinny announced her solo debut under Betty Music on August 1, 2025. Her debut mini-album titled "Towards the Light" was released on September 8, 2025, featuring multiple genres from "high-energy rock-electro fusion to tender ballads and groove-driven R&B".
Particularly significant for Jinny was her creative involvement in the project—she contributed to songwriting and composition, embedding her personal experiences into every track. Her title track "Everglow" was pre-released as a single. About the album's message, she explained it aims "to convey a message of self-confidence and courage to keep moving forward towards the bright future with hard work and persistence".
Jinny's online presence and fan engagement
In preparation for her solo career, Jinny established official YouTube and TikTok accounts to connect directly with her audience. These platforms allowed her to showcase her personality beyond what fans saw during her SECRET NUMBER days.
Her relationship with fans remains particularly meaningful. In a recent interview, she expressed profound gratitude: "I sincerely want to thank all my fans not only for all the love and support, but for always being here and waiting for me, no matter what". She added, "I hope to give back all the love you guys have been giving me, and I hope my existence can be a source of happiness and strength for you all, just like how you guys are my motivation and my inspiration".
Fans have responded enthusiastically to her solo career, with one noting: "Been following Secret Number since debut and although I'm sad they won't be ot6 anymore, the songs Jinny wrote on are my favourites in their discography".
Minji
Park Min Ji, known professionally as Minji, joined SECRET NUMBER as one of two new members revealed in mid-October 2021. Comparatively, her path to K-pop stardom was longer than most, having previously competed in multiple survival shows and trained across several agencies before finding her place in the group.
Minji's role in SECRET NUMBER
As the main vocalist of SECRET NUMBER, Minji brought both technical skill and creative talent to the group. Born on March 31, 1999, in Yongin, South Korea, she had accumulated significant industry experience before joining SECRET NUMBER. Interestingly, Minji participated in both Produce 101 (ranking #71) and Produce 48 (eliminated at rank #53), gaining valuable performance experience despite not making the final lineups.
Officially debuting with SECRET NUMBER on October 27, 2021, through the single album "Fire Saturday", Minji quickly established herself as not just a performer but also a creator. She contributed to the group's musical direction by helping compose their song "Hola" from the "Doomchita" album, showcasing her behind-the-scenes talents alongside her vocal abilities.
Why Minji left SECRET NUMBER
On April 4, 2025, after approximately three and a half years with the group, Minji announced her departure alongside Dita and Jinny. The trio released a joint statement declaring that their "contract with Vine Entertainment has been officially terminated, and therefore, official activities as SECRET NUMBER have now come to an end".
In their collective statement, they explained: "We've always gave our very best, but despite numerous discussions, we ultimately came to the conclusion that under the current situation, it would be extremely difficult for us to move forward". This announcement occurred just one day after fellow member Léa had also left the group, creating a significant turning point for SECRET NUMBER.
Minji's OST and acting projects
Even before her SECRET NUMBER departure, Minji demonstrated versatility beyond idol activities. Most notably, she contributed to drama soundtracks, singing an OST titled "I talk, You Smile" (난 얘기하고 넌 웃어주고) with Baek Myunghan for the drama "Triple Some 2". This opportunity highlighted her vocal abilities in a different context from her group performances.
Minji's creative pursuits in 2025
Throughout her career, Minji has consistently shown passion for music creation. Apart from her contributions to SECRET NUMBER, she has written and composed songs for other artists, including:
"White Day" for Cotton Candy
"Look At Me" for Japanese artist Kawaguchi Yurina
Her compositional skills have been officially recognized through registration with KOMCA (Korea Music Copyright Association), establishing her credentials as a legitimate songwriter and composer.
In March 2020, Minji launched her own YouTube channel where she posted covers, including Billie Eilish songs. Given her background in piano playing and composition, this platform allowed her to showcase her musicality beyond the constraints of group activities.
Presently in 2025, Minji continues to focus on her creative endeavors, drawing from her extensive experience—nearly nine years as a trainee—and her multifaceted talents in singing, songwriting, and performing to forge her post-SECRET NUMBER path in the entertainment industry.
