Yamada Kousuke

Mutsumi likes Hagiwara-senpai, but she's afraid of being rejected if she confesses. She asks her friend Yuka, who has lots of dating experience (within her dreams...) for advice. Yuka suggests sex appeal, but since Mutsumi has no confidence, Yuka tells her to find a boy, someone she doesn't even see as a member of the opposite sex, to test ideas on. In walks Inose Tatsuo, who Mutsumi sees as the perfect guinea pig. Of course, when Mutsumi asks Inose to help her out, he mistakes her for asking him to go out with her. In trying to find out what boys like, Mutsumi will be quite bold, but is Inose's position enviable or pitiable
