Koharu and Yusuke have been dating for two years. Yusuke, who likes each other and lives together, is crunchy and unreliable, but Kokoroharu feels happy as it is. Yusuke is dissatisfied with Kunio's senior at Yusuke's school, who recently put on something and put out a little bit in his heart. But I can't say anything ... One day, Yusuke, who can't say anything when Kunio-senpai proposes to have a hot pot at Shinshun's house, reluctantly gives OK, but I'm not really worried.
