Formed and managed by Vine Entertainment, Secret Number is a six-member girl group that debuted in 2020. Originally launched with five members, the group has gone through a couple of lineup changes over the two years since their debut.

As of July 2022, the girls have released four singles, with “Doomchita” (둠치타) being the most recent. A subunit of three members has also appeared on the soundtrack of the hit K-drama A Business Proposal — they sing an alternative version of the main OST, “Love, Maybe,” originally sung by the duo MeloMance.

Secret Number debuted with the single “Who Dis?” on May 19, 2020. The group was announced in December 2019 and was supposed to debut in March 2020, but the beginning of the COVID-19 pandemic slightly delayed those plans. A dance cover video posted to YouTube and individual introductions on Instagram revealed the five original members: Jinny, Léa, Soodam, Dita, and Denise.

After the first few months of their debut, by the end of 2020, the group achieved commercial success and was named Rookie of the Year at several Korean award shows.

Now a six-piece, Secret Number consists of Léa, Dita, Jinny, Minji, Soodam, and Zuu. If you want to know more about each of the members, their ages, and where they are from, all you need to do is keep reading.
