From Aerandria Scans:

Higashisanjou Ayako is called the queen of Hibarigaoka Academy – she’s smart, beautiful, cool, and practically perfect at everything she does. However, little does everyone know that she has another side to her. One day, Yuzuki Haruka, who everyone calls the king of the academy, finds out Ayako’s secret. Will our queen have a peaceful and perfect life again with her secret in the hands of this little sadistic king?
