Ba Ram, Seung Hyeon, 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 Hyeon doesn't believe in love and all he want is spend each night with a different girl, Sun 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 Hee. Though all of them work in the same building there is no relation between them...or at least that's what they think.
