Miharu is strong and beautiful to the point that he's called "black leopard" in the underworld. Although he's always picking fights everyday, he's actually being "disciplined" by Yashiki, a calm and S guy. However, Yashiki can no longer see out of his right eye. Eventually, that eye's secret, and his gentle kiss takes Miharu by surprise!
