Senri's a real champ for trying to help Chiru keep her innocence, but I wonder how long that's going to last. Senri's experiencing "Kase-san Syndrome", wherein she's in love with an innocent who somehow never thinks about sex (the Yamada) while Senri herself is starting to get hyper-aware of it. For Senri's sanity, we can only hope that Chiru comes out her shell before they have to move the cast to a different city.
