ROE-153 My teacher is my mother's lover

Yuka's mother has been living with her son Yugo since her husband passed away. Working hard on his own, Yugo grew up healthy and became a student aiming for a first-class university. From now on, hard work will be rewarded, and if Yugo becomes a member of society, a happy life awaits him... as it should be. In the summer before Yugo's graduation the following year, Mizuno and his parents consulted their homeroom teacher, Oshima. After a favorable three-way meeting, Yuka, left alone in class, is informed that there is a problem with Yugo continuing in college.
