Very Private Lesson

Oraku's life seems ordinary: he teaches at a local high school, has a potential partner in Satsuki, and harbors romantic feelings for her. However, his life takes an unexpected turn when Aya, a beautiful student, moves in with him at the behest of her father, a powerful crime boss who insists on her purity. As Aya's presence in his life becomes more complicated, Oraku must balance his desires with the danger that comes with being linked to a major crime boss and, at the same time, navigate the challenges of keeping his relationship with Aya a secret from the rest of the school.
