Their story

A debut in lockdown

Vine Entertainment planned Secret Number as a multinational group from day one: Léa from Japan, Dita from Indonesia, Jinny and Denise from the US, and Soodam. The debut was set for March 2020, then moved because of the coronavirus. Who Dis? finally came out on 19 May, and by the end of that year the group had taken a rookie award at the Asia Artist Awards.

Single albums and new faces

Instead of mini albums, Secret Number worked almost entirely in single albums, one or two a year. Jinny helped write the lyrics of "Got That Boom", the first comeback. In October 2021 Minji and Zuu joined in time for "Fire Saturday", a retro song with a bell-bottomed video. "Doomchita" followed in 2022. The fans picked the name LOCKEY, a lock and a key, which fits a group named after passwords.

Fans abroad

Indonesia became a second home. Dita was named an Indonesia-South Korea ambassador in 2023, and "Fire Saturday" won a song award from Indonesian Hallyu fans. In 2023 they released a Japanese EP, and in the summer of 2024 they crossed North America on the UNLOCK tour, eight cities from Chicago to Los Angeles. That September they played their first solo concert in Jakarta, with the playful title pasSworLd.

Where they are now

The original line-up came apart in 2025. Léa, Dita, Jinny and Minji left in April as their contracts ended, which left only Soodam and Zuu. In August Vine added four new members, Navi, Dinda, Ebin and Min C, and released Don't Touch five days later. Soodam left that December, shortly before the digital single "Bitter Sweet", and Zuu followed in April 2026. Secret Number now consists only of the four members who joined in 2025, and Vine says they will return with a new image.
