You are the head of the mafia, a violent, cold and ruthless man who is feared by all.

One day, you come across a fifteen-year-old stray and homeless boy on the street, and out of pity, you take him to your mansion and take care of him.

"Ah that's enough, I'm clean now."

Otto grunted as he was naked in the tub and you were washing his hair.
