After an unintentional comment, Iori Shino, a virgin, becomes engaged to Tendo Tsukasa, a well-known and wealthy celebrity on campus. Although rumors suggest that Tsukasa has sexual relations with anyone, Iori finds himself bewildered by their differences in expertise and familiarity. However, as they spend more time together, Iori becomes fascinated by Tsukasa's unpredicted depth. This slightly mature romantic comedy coming-of-age tale portrays their journey to understand their feelings as two opposites in love. (Translated from Comic-Walker/NicoVideo).
