Rush (1999)

Ba-ram, Seung-hyun, Sun-woo and Sang-jin are a group of young Koreans that spend all their time chasing their dreams. Ba-ram is the leader of a rock band and for her there isn't nothing but her music. Seung-hyun doesn't believe in love and all he want is spend each night with a different girl. Seon-woo only dreams about being a powerful person and the only goal of Sang-jin is to find the true love and take care of her little sister, Sang-hui. Although all of them work in the same building, there is no relation between them...or at least that's what they think.
