Tsukiwaka might be a fan of cute and girly things, but actually he can't handle women well. One day, a strange, beautiful woman named Hinako showed up on his campus. She handed a hand-made lunch box to Tsukiwaka while smiling, "I am your wife." Since he is bad with women, Tsukiwaka thought he could resist such an unexpected self-declaration, but why does Hinako make his heart race? Should Tsukiwaka go along with her play?
