Hairstylist, Kusaka Akira and his lover, Shimizu Ken have promised each other to go independent and open a hair salon together one day. Their shop manager and fellow staff are supportive of their love and dream and the peaceful atmosphere in the shop continues until they take in a new staff who had caused trouble at his previous workplace. The newbie, Nagasawa Roka, is a shy and highly wary person but for some reason, Akira is the only person he became attached to. Also, somehow, it seems that Roka has a personal grudge against Shimizu?
