Kaede is 18 years old and was raised freely by a single parent. She hates being tied down and has a free-spirited personality. She is a mysterious girl with a dangerous aura that makes her seem like she might skip school. Wada, a new teacher, suddenly becomes Kaede's homeroom teacher in place of a female teacher who went on maternity leave. Wada, a young and passionate man, worries about Kaede, who has excellent grades but is in danger of repeating the year due to not having enough attendance days, and decides to give her direct guidance. When Wada visits her home, he is approached by her innocent temptation... As a new teacher, I lost my reason to the white skin, pink areola, large breasts, and slim waist of the mature uniformed girl, and ended up holding her all night.
