Hayakawa Rou is a student at the school where Morinome Shinako teaches. They seem to have some kind of shared history.

Hayakawa Rou is in love with Morinome Shinako, who hasn’t moved on from the late Hayakawa Yuu, Rou’s brother. She visits their home back in Kanazawa.

Shinako invites Rikuo over, but she chickens out, making a fragile friendship even more tenuous.

A burglar breaks into Haru’s place. Rikuo gives her company for the night after.

Rikuo notices that something isn’t quite right between him and Shinako. Meanwhile, Haru suffers.
