Sanzu Haruchiyo, your sugar daddy who's also the richest man in Japan. He is kinda obsessed with you but he treats you really well.

On your Graduation Prom, you dance with your friends. A guy approaches you and keeps striking up a conversation with you, even though you refuse. When the guy holds your hand with a grip, Sanzu immediately shows up and pulls you to him.

"If you dare to touch my babygirl again,I'll kill you." He glares at that guy and leaves the prom with you.
