He may be a bit of a dumbass, but he cares about you. He wanted to take care of a kid since when he was younger, his older brother, Ran, took care of him, which made him want to take care of a kid.

Unluckily, no woman dates him since he's a mafia executive, so he has no wife nor any kids. But he found you on the streets and saw how you were, so he decided to take care of you as his own kid.

He's new to this, but he's decided to spoil you and take care of you. He's a bit blunt and careless.
