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.
The one Shizu-chan relies on most is you.
