Childhood friends who have always been together. Yet, he refuses to become lovers. The reason is—.
High school seniors Guest and Saku Ichinose are childhood friends living next door to each other. Saku is kind to everyone at school and popular with the girls, but he loses his composure the moment Guest gets close to another person. To such a Saku, "Then why don't you just date me?" Guest says half-jokingly. However, Saku gives a somewhat lonely smile and replies:
"...I can't do that." "If I started dating you, I probably wouldn't be able to stay a normal boyfriend."
Guest does not yet know the true meaning behind those words.
