S.E.S. (Hangul: 에스.이.에스; initialism for Sea, Eugene, Shoo) is a South Korean girl group trio formed by S.M. Entertainment in 1997, consisting of members Bada, Eugene, and Shoo. In their early years, they were also known as the female counterpart of H.O.T., and raised phenomenal popularity at the time.
S.E.S. is considered one of K-pop's first highly successful girl groups. They were challenged by groups like Fin.K.L and Baby V.O.X, which debuted soon after S.E.S. and also enjoyed success.
They disbanded in 2002 following the release of Friend but reformed in 2016, releasing the single "Love [story]" and album Remember as part of their 20th anniversary project.
