Nishihiro, the boy who is bad at human relationships, secretly harbours romantic feelings towards his one and only friend, Nakano. Even though he never intended to reveal his feelings, he's caught by the playful Kutou. Then, as a joke, Kutou expressed that he likes Nishihiro and that he can depend on him next time. Although he refused Kutou's suggestion, because of Nakano, he's unconsciously clung to Kutou's side.
