Subaru, a college student, loses only part of his memory in an accident. It is a memory of "living together" with a high school classmate, Soushi. At that time, he was sure he hadn't talked to the guy who's cool and popular, unlike himself. Subaru who was discharged from the hospital, started living together, and learned about Soushi again.
