Nozomi tried to get to know Haneda but he was a shy person and seemed distant to her. After a period of research, Nozomi found the reason why Haneda couldn't concentrate on studying was because Haneda's physiological needs were too high but he didn't have a girlfriend so he only knew how to watch sex and turn around. What will Nozomi do to help Haneda?
