Alt. title: バックステージ・ラヴァーズ.
Niwa Ikusei lives night to night in the homes of random girls while he attends music college. Ikusei runs into a senior of the composer’s department , Yui Mahiro as he makes a girl cry–! Even though he is the son of a genius pianist, Yui is in the composition department. Issei, who fell in love with his music, involved Yui in his band for the cultural festival. Yui, who is usually awkward and unfriendly, has a pure, stoic side and Issei finds it absolutely endearing.
