While Miyako takes a nap next to Hinata and others eating sweets on a bench, Koko quietly approaches Miyako from behind. Hinata notices her and shouts, causing Miyako to wake up and collide with Koko's head. She then describes that she had a crush on Miyako from high school and begins to obsess over her.
