First-generation K-Pop girl group S.E.S. returns after 14 years. They are preparing for their year-end concert "Remember, the Day" on Dec. 30 and 31 at Sejong University in Seoul, South Korea.

S.E.S. stands for the trio's names Sea (Choi Sung-hee aka Bada), Eugene (Kim Yoo Jin) and Shoo (Yoo Soo Young). Formed in 1997 by SM Entertainment, it was K-Pop's first highly successful girl group before the members went solo to various degrees of success.

S.E.S.'s famous songs include "I'm Your Girl," "Love" and "Show Me Your Love." During their time, members of idol groups were not allowed to do individual promotions so the trio parted ways in 2002.

Sea, Eugene and Shoo took to S.M. Station, SM Entertainment's digital music platform on Nov. 28, Monday, to announce their latest single "Love [story]." The song is a mashup of the group's hit singles "Love" and "I'm Your Girl" and was produced with the agency's leading composers. It is part of Remember, the group's long-term project to commemorate their 20th debut anniversary in 2017.

S.E.S.'s official comeback with project Remember includes the band's own reality show "Remember - I'm Your S.E.S.," which will debut on Dec. 5 via Oksusu app, the two-day concert and the release of the first of their songs. The first of their title tracks will be out on Jan. 1, 2017 while the second and the full album will be released on Jan. 2, 2017, Soompi reported.

The group also came together in 2007 for their 10th anniversary and appeared on "Happy Sunday" in 2008. In 2009, the girls appeared as guests on "Come to Play."

The girls got together again in 2014 for "Infinite Challenge" special entitled "Saturday Saturday Is a Singer." Eugene was pregnant at that time so she was substitued by Girls' Generation Seohyun, All KPop reported

On May 28, S.E.S. attended a charity event Green Heart Bazaar. In October, they announced their official return to the music scene via Sea's Instagram post.
