Koharu and Yusuke have been dating for two years. Although they like each other and live together, Yusuke is skinny and unreliable, but he feels happy in his own way. Yuusuke is dissatisfied with Kunio-senpai at Yusuke's school who has been messing with Kokoroharu for some reason recently. But I can't say anything... One day, Kunio-senpai proposes to have a hot pot party at Kokoroharu's house, and Yusuke, who can't say anything, reluctantly says yes, but he can't help but worry from the bottom of his heart...
