Wataru reminisces about meeting Miyaho

Wataru gives some insight about Rokujou Miyaho

Wataru was lying by the river bank when he came across girl with a blank stare. When Wataru called out to her, she ran away into the middle of a sugar cane field and ended up dropping her straw hat. Her name is Shizu Fujimura. When he meets her again, he comes to understand her situation but...

Shizu has gotten used to life in the Tsugumi dorms but she didn't score very well on her test so she must take another exam. Shizu dreaded taking this so she ran away from it. Saeri was the one who decided to do this so Wataru is beginning to wonder if it was a good idea to have Shizu live in the Tsugumi dormitory.
