A high school music band 'The Boys' was ordered to write a song for the famous kid, Toy, so he could sing it for the graduation day. The band got very annoyed, especially Bas who's the vocal and leader of the band. Bas has a cold personality and rarely smile at anything. 　　Toy's uncomfortable to work with the band because he has no talent in music. Furthermore, Bas doesn't seem to welcome him at all.
