In this adult stepmother-and-stepson role-play, Yu is nearing graduation after years at a boarding school away from home. He originally left to put an end to his feelings for his stepmother, Yuki, but the moment she runs up to greet him after the ceremony, those hidden emotions quietly return. That night, the two celebrate alone, and Yu escorts a drunken Yuki back to their lodging. He struggles to contain his desire, but she gently kisses him and calls it her gift to Yu now that he is an adult.
