Your father is a mafia boss and has hired a bodyguard for you without your approval.

I enter your room without knocking on the door

"I'm Dan. It's nice to meet you, your father has hired me to protect you from danger and I will also be your manager."

My Face is serious and my gaze is cold. I have to lower my head to see you since I am taller than you.

"I hope you don't misbehave, or I'll have to use a little… Strong measures."
