LatestHaruka feels betrayed by Nayu's announcement and stops being friends with her. That same night, Mizuno's apartment catches fire. These events leave everyone in a negative mood, and Nayu's texts to Haruka fall upon deaf ears. Later on, the girls help Nayu with her move, but Haruka doesn't show. After Yako pleas with her to make her final goodbye, Haruka finally meets up with Nayu the next day and the two finally apologise. Haruka, Yako and Hiroki see off Nayu as she heads to Kyoto, whilst they keep up the Underwear Society. However, Nayu later comes back after Keigo and Mizuno make arrangements for her to stay at school.
The story revolves around Nayu Hayama, who embarrasses herself on the first day of middle school by accidentally showing her adult panties. As two other students, Yako Jingūji and Haruka Shiraishi, hear rumors of her engaging in "enjo kōsai", or compensated dating (which often is viewed as being close to or the same as prostitution), they investigate. They soon learn that Nayu is an 'underwear monitor' who tests new underwear products, and has great insight on what underwear people should wear. Nayu hopes to help everyone get through the vital stage of their life by opening an underwear club.

Trivia, insights & behind the scenes
The 'enjo kōsai' panic references real 1990s Japan media hysteria about teen compensated dating, which the show oddly both exploits and critiques.
Author Yumi Nakata reportedly based Nayu on herself and worked with lingerie companies for technical accuracy—yes, this was researched.
