Kamijou is just an ordinary guy, while his ex-childhood friend, Aikawa Itasu, is a well-known and clever girl. Feeling that Aikawa is on a different level from him, Kamijou tries to keep his distance. However, one day, Kamijou's cat named Peace wanders off and visits Aikawa. This leads to the two of them rekindling their friendship. There's a question, though: Why did Aikawa feed Peace? And will they be able to reconnect on a deeper level?
