Their 1st album released in March '99 was extremely well received all over. This maxi-single from S.E.S. (coming out after 8 months since the group's debut in Japan) is the ending theme song for Fuji TV's show ''Koi Girl Koi Boy''. The song is laso the leading track from their first album, re-recorded and presented here as a remix single. Also contains 2 new songs plus an instrumental track. A total of 4 tracks.
