Last summer, Wakahayashi, a die-hard lolicon teacher who transferred from a city school to a rural one, obtained his teaching license and took the job solely to have perverted encounters with young girls. However, at his new school, strict supervision made it nearly impossible to approach female students, leaving him increasingly frustrated. Seeking a way to fulfill his desires, he devises a plan—focusing on female students with low academic scores who still aim for college. Under the guise of career counseling, he invites these girls to his home, pretending to discuss their futures while building intimacy. As a result, Rena, a girl hoping to attend university in Tokyo, is invited to his house without realizing his true intentions. Unaware of Wakahayashi's real motives, she heads to the teacher's home.
