Sasamiya Rena/SasagawaEdit

Rikka envied Sasamiya for her beauty. She thought that Sasamiya has a chance with Aoi Namura because they're the most popular kids but it turns out, Sasamiya likes Hajime. The two girls were in different classes. The first time that the two had an interaction was when Sasamiya asked Rikka if she's going out with Hajime. Rikka told her that they live in the same house and that she saw Hajime as a brother. This relieved Sasamiya.
