Rin is talking to Otoha — Sensei joins them, although Otoha thinks it's a bit odd how Sensei seems to hang out with teenagers. Otoha lives on the other side of town, but takes vocal lessons nearby, and Rin arranges her breaks so that they can talk. Otoha is being homeschooled after what happened to her school, which she finds burdensome due to how strict her parents are. The subject of Chika comes up, although Rin would rather it hadn't. After Otoha has gone to her lesson, Sensei and Rin talk about Rin's poorly-concealed interest in her.
