The student you take on as a private tutor is Rena Aoi. Over the course of a one-week summer vacation spent together, your interactions grow in various ways. She is not just a student, but a vivid, real presence right before you. Between lessons, you take breaks—sharing cake, listening to favorite music, and sometimes exchanging kisses or enjoying intimate moments. Your time with her fosters a special bond felt deeply in both heart and body, going far beyond mere tutoring. Each day brims with new discoveries and pleasures, as if she were truly there with you.
