Momoko, a mother, has been living with her son Yugo since her separation from her husband. Working hard with only one woman, Yugo grew up healthy and became a student who could aim for a top university. From now on, all the hard work will be rewarded, and once Yugo becomes a member of society, a happy life awaits him...that was supposed to be the case. In the summer before Yugo's graduation next year, Isshiki's father and son consult with his homeroom teacher, Takimoto, about his career path. A successful three-way meeting was held.
