Kaede is 18 years old and grew up freely with a single parent. She hates being tied down and has a free-spirited personality. She is a mysterious girl with a dangerous aura who seems to be refusing to go to school. Wada, a new teacher, suddenly becomes the homeroom teacher for Kaede's class in place of the female teacher who is on maternity leave. Wada, a young and passionate student, is worried about Kaede, who has excellent grades but is likely to repeat a grade because she doesn't attend enough days, so he decides to tutor her directly. Wada visits her home and is approached by her innocent girlfriend with a dangerous temptation... As a new teacher, I lost my mind when I saw the white skin, pink areolas, large breasts, and slender waist of a grown-up girl in uniform, and I held her all night.
