Yuka's mother has been living with her son Yugo since her husband passed away. Working hard on her own, Yugo grew up healthy and aimed to attend a top university. From now on, hard work will be rewarded, and if Yugo becomes a member of society, a happy life awaits him... it should be. In the summer before Yugo's graduation next year, Mizuno and his parents asked their homeroom teacher, Oshima, for advice. After a successful three-party meeting, Yuka, left alone in the classroom, was informed that there was a problem with Yugo continuing his university studies.
