Rina hates perverted guys. She can't seem to find the prince she so desperately seeks. That's before she meets the new transfer student. Behind his hair, she discovers the face of her prince. But it starts getting weird when he sniffs her butt.

Turns out that there is good reason--he was raised by wolves. How is Rina going to deal with the new object of her affection when said person is a true wolf?
