S.E.S.

S.E.S. (에스이에스; initialism for Sea, Eugene, Shoo) was a South Korean girl group trio formed by SM Entertainment in 1997, consisting of members Bada (바다, known also as Sea), Eugene (유진), and Shoo (슈). 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.
