Her Underwear Club ruined by the peeping tom incident, Nayu feels depressed. She turns to Keigo Hayama, the step-brother she has been living with since her parents passed away, for support. Feeling responsible for the incident, Komachi turns up on Nayu's doorstep to encourage her to form an appreciation society instead of a club. With the decision to form an Underwear Society made, Nayu invites Yako, Haruka, and their advisor Tamaki to an overnight meeting. However, Nayu cannot get Kiyono Amahara's words off her mind.
