Campus daily life is joyful + slightly dark. The heroine is neither Su nor the Virgin.
Akane Igarashi, an eldest lady with outstanding skills but little achievements, spends her days sleeping and eating in Hyotei because of her father's instructions not to provoke Master Keigo of the Atobe family. By some strange combination of circumstances, she still fell in love. Before meeting Atobe, she would never have imagined that she would have a gorgeous and dangerous love affair. Regardless of anyone's warnings, she never gave up on love. Faced with her lover's initial loyalty and later cheating and betrayal, she was the only one who didn't know the truth that everyone knew. He is a proud man who would rather miss something than go too far. She just hopes that the years will be peaceful and the world will be stable.
