What if a K-Pop group could speak directly to fans in Jakarta, Tokyo, Los Angeles, and Seoul — all at the same time? That is not a hypothetical. That is exactly what Secret Number members have been doing since their debut in 2020, and in 2024, the world is finally catching up to what dedicated fans already knew: this group is something genuinely special.
In a music industry overflowing with girl groups, Secret Number carved out a lane that very few have managed to occupy — multinational, multilingual, and undeniably talented. While many K-Pop groups market themselves as “global,” Secret Number actually lives that identity through the diverse backgrounds of every single member on their roster.
Whether you are a longtime fan looking for a comprehensive member guide, or a curious newcomer who just discovered them through a viral clip, this article covers everything you need to know. From detailed member profiles and career highlights to their cultural impact on the Hallyu Wave, consider this your ultimate guide to one of K-Pop’s most compelling and rapidly rising girl groups.
What Makes Secret Number Different From Other K-Pop Girl Groups?
Before diving into the individual Secret Number members, it helps to understand why this group stands apart from the hundreds of K-Pop acts competing for global attention.
The Group’s Origin Story
Secret Number was formed and launched by Vine Entertainment with a debut that arrived on May 19, 2020 — one of the most challenging periods in modern entertainment history. Despite debuting during the global pandemic, the group generated significant buzz, largely because their concept felt fresh and authentically international from day one.
The group originally consisted of Léa, Dita, Jinny, Soodam, and Denise, debuting with the single album Who Dis? Rather than assembling an all-Korean lineup and adding international appeal through marketing alone, Vine Entertainment built internationality into the group’s very DNA — with members recruited from South Korea, Indonesia, Japan, and the United States.
Their debut single Who Dis? was produced and composed by Melanie Fontana, who has worked with famous artists like Halsey, Justin Bieber, SIA, and Dua Lipa — a remarkable production pedigree for a rookie group, and a clear signal that Vine Entertainment had serious global ambitions from the very beginning.
Their Signature Sound and Style
Musically, Secret Number sits at the intersection of pop, R&B, and dance-pop — a combination that feels both polished and accessible. Their debut track immediately announced a confident, mature concept that set them apart from the innocent or cute aesthetics many rookie groups lean on.
Their choreography is precision-driven, their vocal harmonies are layered, and their visual presentations consistently reflect a group that takes artistry seriously. Fans who appreciate groups like TWICE for their performance precision or BLACKPINK for their bold concepts will find plenty to love in Secret Number’s discography.
Why They’re Gaining Momentum in 2024
Several factors converged to push Secret Number into wider global consciousness in 2024. In early 2024, Secret Number announced their debut concert tour in the United States titled Unlock, visiting eight cities chosen by fan polls, starting from Chicago on July 26, 2024, and ending in Los Angeles on August 10. Later that year, in September 2024, Vine Entertainment held the group’s first solo concert titled Passworld in Indonesia, at Tennis Indoor Senayan, Jakarta.
These milestones — a full US tour and a major solo concert in Indonesia — represent genuine proof of an international fanbase that has been quietly growing for years and was ready, in 2024, to show itself in full.
Secret Number Members — Full Profiles and Roles Revealed (2024 Lineup)
This is the section you came for. Below is a comprehensive, verified breakdown of all six Secret Number members as they stood in 2024 — their backgrounds, roles, personalities, and what makes each one essential to the group’s identity.
1. Léa — The Japanese Leader Who Paved the Way
Birth Name: Ogawa Mizuki (小川 美月)
Nationality: Japanese
Birthday: August 12, 1995
Position: Leader, Lead Vocalist
Léa was born in Tokyo, Japan, and is the tallest member of the group. She is also the eldest — and in Secret Number, age and experience translate directly into leadership. Although there is no official leader position assigned in the team, in practice Léa acts as leader by checking the group schedule and taking care of other members.
Léa’s journey to Secret Number is one of the most remarkable pre-debut stories in recent K-Pop history. She was previously a member of the Singaporean-South Korean girl group Skarf between 2011 and 2014 under the stage name Hana, and later participated in the survival show Mix Nine under her birth name Mizuki Ogawa in 2017, finishing in 109th place. After the disbandment of Skarf and her elimination from Mix Nine, she gave up her dream of being a singer and returned to Japan — but after persuading her parents, she returned to Korea and eventually debuted with Secret Number.
That perseverance story resonates deeply with fans. Léa did not have an easy path — she rebuilt her dream from scratch, across multiple languages and countries, and debuted at 24 years old with the maturity and resilience to show for it.
As the group’s lead vocalist, Léa is in charge of lead vocals, and although she is sometimes perceived as a sub-vocalist due to her parts being stylised, her vocal skills are outstanding. Her Korean fluency, developed through years of living and training in South Korea, also makes her an effective communicator across the group’s diverse membership.
💡 Notable Pre-Debut Fact: Léa was active as a child actress in Japan during her elementary school years, and received street casting from several Korean agencies — including three major ones — when she was shopping with her mother in Shibuya, Japan.
2. Jinny — The Korean-American Rapper With a BLACKPINK Connection
Birth Name: Park Jin Hee (박진희)
Nationality: Korean-American
Birthday: January 20, 1998
Position: Main Rapper, Lead Dancer, Lead Vocalist
Of all the Secret Number members, Jinny may have the most jaw-dropping pre-debut story. Originally a trainee under YG Entertainment, Jinny was a pre-debut member of BLACKPINK, but was cut from the final lineup. She trained alongside Jisoo, Jennie, Rosé, and Lisa as part of a group of trainees known internally as “Pink Punk” — and was not selected when the final BLACKPINK lineup was confirmed.
Jinny was born in Los Angeles, California, and is fluent in English and Korean, with some ability in Japanese, Indonesian, Mandarin, and Spanish. Her multilingual range makes her one of Secret Number’s most versatile communicators, and her Korean-American background gives her a genuine cultural bridge to English-speaking fans worldwide.
As the group’s main rapper, Jinny brings sharp, confident delivery to Secret Number’s more uptempo tracks. Jinny wrote the rap lyrics for the debut single “Who Dis?” — a fact that speaks to her creative involvement in the group’s output from day one, not merely as a performer but as an active contributor to their artistic identity.
Jinny participated in the survival show Produce 48 where she finished in 69th place before eventually finding her way to Vine Entertainment and Secret Number.
💡 Fun Fact: Jinny is a dedicated fan of BIGBANG and 2NE1 — the very artists signed to the label where she trained for years. Her admiration for YG artists is part of what drew her to pursue Korean entertainment in the first place.
3. Dita — The Indonesian Star Rewriting K-Pop’s Boundaries
Birth Name: Dita Karang
Nationality: Indonesian (Balinese ethnicity)
Position: Main Dancer, Vocalist
If there is one Secret Number member whose presence carries cultural significance beyond music, it is Dita Karang. Dita is from Yogyakarta, Indonesia, and is Balinese by ethnicity. She made history as one of the very few Indonesian artists to debut in a mainstream K-Pop group, and the impact of that representation cannot be overstated.
As the group’s main dancer, Dita brings physicality and grace to Secret Number’s choreography that elevates every performance. Dita is also a member of 1MILLION Dance — one of the most respected dance studios and creative collectives in the K-Pop world — which speaks directly to the serious professional level of her dance training and credentials.
Beyond dance, Dita’s multilingual ability — communicating in Indonesian, Korean, and English — makes her remarkably accessible to a wide international audience. In April 2024, Dita was chosen to be the brand ambassador for the health product brand Femmy Fyber, reflecting her growing commercial profile in her home market.
Cultural Significance: For millions of K-Pop fans across Southeast Asia, seeing Dita on a K-Pop stage is deeply meaningful. She did not just join a group — she opened a door, and the Indonesian FNS fan community is among the most active in the world as a direct result.
💡 Fun Fact: Dita’s best friend in the group is Jinny — a friendship between the Indonesian member and the Korean-American member that reflects the genuine cross-cultural bonds Secret Number has built internally.
4. Soodam — The Visual Center With Deep Korean Roots
Birth Name: Lee Soodam (이수담)
Nationality: Korean
Birthday: November 9, 1999
Position: Lead Dancer, Sub Vocalist, Visual, Center
Soodam is the group’s visual and center — the member positioned at the heart of Secret Number’s performance formations and the face most frequently placed front and center in the group’s visual content. Her role as center reflects a combination of stage presence, visual appeal, and the kind of magnetic quality that draws audience attention naturally.
Soodam studied Korean traditional dance for 10 years — a background that gives her movement a distinctive quality unlike most K-Pop dancers. Traditional Korean dance training emphasizes controlled grace, intentional weight, and emotional expressiveness through physical movement, all qualities that translate into a performance style that feels notably different from standard K-Pop choreography training.
Soodam was once a member of the traditional dance group Little Angels Children’s Folk Ballet of Korea — a prestigious performing arts group that has performed internationally. This means Soodam was a professional performer long before the K-Pop trainee system, which adds a depth of stage experience to her profile that is genuinely unusual.
💡 Fun Fact: Soodam’s name literally means “shining pond.” Fans consider it a fitting name for a member whose quiet, graceful presence tends to catch the eye without demanding it.
5. Minji — The Main Vocalist Who Almost Debuted Twice Before
Birth Name: Park Min Ji (박민지)
Nationality: Korean
Birthday: March 31, 1999
Position: Main Vocalist
Minji joined Secret Number in October 2021 as one of two new members added alongside Zuu — but her journey to that debut had already been a long one. Minji previously participated in the survival program Produce 101 but was eliminated in episode 5, and also participated in Produce 48, finishing in 53rd place.
As the group’s main vocalist, Minji carries the heaviest vocal responsibilities on Secret Number’s most demanding tracks. Her voice has the kind of controlled power that sounds equally impressive in studio recordings and live performances — a consistency that is one of the truest marks of genuine vocal ability.
Minji spent almost 9 years as a trainee before debuting with Secret Number — nearly a decade of preparation that is a testament to her dedication and the resilience required to keep pursuing a dream through repeated near-misses. That backstory resonates deeply with fans who have followed her journey.
Minji helped compose Secret Number’s song “Hola” and “White Day” from the drama series IDOL: The Coup, showing that her contribution to the group extends beyond performance into creative songwriting.
💡 Fun Fact: Minji is friends with Jeon Somi and Kim Doyeon — two of the most prominent figures to emerge from the Produce 101 franchise, reflecting the tight-knit community that formed among that generation of trainees.
6. Zuu — The Energetic Maknae Completing the Lineup
Birth Name: Ji Yeongju (지영주)
Nationality: Korean
Birthday: March 24, 2000
Position: Lead Dancer, Lead Vocalist
Zuu was born in Seoul, South Korea, and was revealed as a new member of the group in October 2021. As the group’s maknae (youngest member), Zuu brings a youthful energy and enthusiasm to Secret Number that balances the group’s more experienced members beautifully.
As both lead dancer and lead vocalist, Zuu occupies a dual role that demands versatility. Her dance ability gives Secret Number additional strength in their performance formations, while her vocal contribution adds texture to their harmonies. The combination makes her a quietly essential member — not always the most visible in individual fan discussions, but unmistakably present in every performance.
Zuu was a student of Art One Academy for 3 years — a notable training background that reflects the serious preparation she brought to her debut with the group.
💡 Fan Note: Zuu is known within the LOCKEY fandom for her enthusiastic, energetic stage presence — the kind that makes live performances feel genuinely exciting from the moment she steps on stage.

Secret Number’s Musical Journey — From Debut to 2024
Debut Era — “Who Dis?” (2020)
When Secret Number dropped “Who Dis?” on May 19, 2020, the K-Pop community took immediate notice. The debut single album consisted of two tracks — the lead single “Who Dis?” and “Holiday.” The production was sleek and contemporary, blending dance-pop energy with R&B undertones in a way that felt mature without being inaccessible.
On May 23, it was announced that the music video for “Who Dis?” had surpassed 5 million views — a strong milestone for a rookie group debuting during a global pandemic. Secret Number’s commercial success in their first five months earned them several rookie awards at major Korean year-end music award shows, including the Asia Artist Awards, APAN Music Awards, and Asian Pop Music Awards.
Key Releases and Comebacks
Secret Number released their second single album Got That Boom on November 4, 2020, followed by Fire Saturday on October 27, 2021 — which also marked the introduction of new members Zuu and Minji.
Subsequent releases included Doomchita on June 8, 2022, and Tap on November 16, 2022. Each comeback added new sonic dimensions to the group’s identity — from the high-energy impact of Got That Boom to the more layered production of later releases.
In 2023, Secret Number released their first Japanese extended play Like It Like It, with the single of the same name on April 5, followed by two single albums — Doxa on May 24 and Starlight on August 16. The Japanese EP marked a significant milestone — an official expansion into one of K-Pop’s most important international markets.
2024 — Their Biggest Year Yet
2024 was unambiguously Secret Number’s most ambitious year. The US Unlock tour across eight cities, followed by the Passworld solo concert in Jakarta, demonstrated that their fanbase had grown to a scale that could support real international touring activity. For a group that had spent four years quietly building a global following, 2024 was the year that following announced itself publicly.
Why Secret Number Matters for the Future of K-Pop
Diversity as a Strength in the Hallyu Wave
The Korean Wave has achieved genuine global mainstream penetration in a way few national cultural movements have ever managed. K-Pop sits at the center of that wave — but for much of its history, it attracted a global fanbase while presenting an almost entirely Korean face to the world.
Secret Number’s model is different. Four of the group’s members were born outside of South Korea — Léa is Japanese, Jinny is Korean-American, and Dita is Indonesian. This is not representation as marketing — it is representation as the group’s actual identity, and fans across the world feel that difference.
Their Impact on Southeast Asian K-Pop Fans
For fans across Indonesia, Thailand, the Philippines, and beyond, Dita’s presence in Secret Number means something that charts and streaming numbers cannot fully capture. She demonstrated that the path to a K-Pop stage is possible for Southeast Asian artists — and the Indonesian LOCKEY community’s extraordinary passion and organizational energy is direct evidence of what genuine representation can build.
Secret Number’s first solo concert in Indonesia, held at Tennis Indoor Senayan in Jakarta in September 2024, was not just a concert. For Indonesian fans, it was a homecoming.
A Blueprint for the Next Generation
Secret Number’s multinational model — genuine, not manufactured — offers the K-Pop industry a blueprint for deepening global resonance in ways that feel authentic. As K-Pop continues its expansion into new markets, the groups that reflect those markets’ actual communities will build the most durable fanbases. Secret Number has been living that truth since 2020.
