TIMELINE
The journey
ORIGIN
Vine's global lineup
2019 — 2020
Vine Entertainment built SECRET NUMBER as a multinational dance group spanning Korean, Indonesian, Japanese and American members, leaning on strong choreography and a sleek, mature concept rather than a domestic-first strategy. The international makeup was the core selling point from the start.
DEBUT
Who Dis? debut
2020 — 2021
Debut single Who Dis? and follow-up Got That Boom established a confident, performance-heavy identity that earned a sizeable overseas following, especially across Southeast Asia, even as domestic chart impact stayed modest.
Anchor track: Got That Boom
BREAKTHROUGH
Fire Saturday & touring
2021 — 2023
Fire Saturday (Doomchita) and Tap pushed the group's polished dance-pop further and supported active international touring, with the multinational lineup driving particularly strong engagement in Indonesia and the broader region.
Anchor track: Fire Saturday
RETURN
Lineup overhaul
2025
In 2025 nearly the entire original lineup departed as contracts expired — Léa, Dita, Jinny and Minji left in April, Soodam in December — and Vine added four new members in August. By 2026, after Zuu's exit, SECRET NUMBER continued as a rebuilt four-member group with no founding members, releasing the single Don't Touch.
Anchor track: Don't Touch
