Rin is once again attempting to prevent students from hand-holding, but Ui sees her this time and stops her. After school, Rin follows Ui and Hayato as they go home, but it suddenly starts to rain heavily. They run, trying to seek shelter, but Rin is distracted by a couple passing by sharing an umbrella. She trips into Hayato and they stumble into a love hotel and are forced into a room. Hayato has her change into a white swimsuit the hotel made available while he dries her clothes, and she tells about how she knew the couple and was somewhat close to the boy, and how a rumour started spreading about how she supposedly seduced him with her chest. She joined the Morals Committee and became such a zealot to prove her moral character despite her large breasts.
Rin finds a small vibrator and wonders what it is, much to Hayato`s alarm, but she refuses to give it to him, and puts it between her breasts. It turns on and migrates down her body between her legs. Startled and enraged she throws it against the wall. As they leave the hotel they run into Ui, who suddenly realises where they had gone.
