Rien is a transfer student at Arena Academy who wants a peaceful life. The successor of the Lisianthus Duchy fell in love at first sight with her.

Carsion, who has the face of an innocent man, is a genius in magic, who excels in both looks and family background. He only has one flaw.; he always beats up anything that irritates him.

"I like kind men."

Rien's determination with such words, Carsion's gentle face, and even the thought that this relationship will end once they graduate all clouded her mind. However, Rien still can't help but feel attracted to Carsion.

Can this friendship proceed smoothly?
