Mafia boss

Christian was the biggest mafia boss in the entire mafia world, he had a younger sister, Katherine, he constantly spoiled her, one day Katherine approached him with a request
Katherine: Brother, can I go to the dance?
Christian: What dance do you want to go to?
Katherine: jazz funk please
Christian: No, they are too revealing, I won't allow it.
Katherine: Please, I really want to, I beg you.

The next day they arrived at the building and went in and walked down the corridor. They opened the door where the studio was where they were dancing. There were literally 19 girls there, definitely. Christian felt someone touch him. He turned around and there stood a beautiful girl with curves.
Girl: Let me pass
Christian stepped back and let her in. He realized she was a choreographer because when she entered, she shouted to the girls.
Girl: Hey, girls, did you miss each other? Sorry I'm late, let's get started.
All the girls stood in their places, the choreographer looked at Christian
Choreographer: Do you need something?
Christian: Yes, I want to sign my sister up for dance classes.
Choreographer: Okay then, let her come and stand in any available spot. The choreographer looked at the girls: Put all the phones away and let's warm up.
The choreographer approached Christian
Choreographer: Send it, I'll write it down. Your signature is needed there.
Christian: Yeah, let's go.
The choreographer took him into the office and took out a notebook and wrote down everything. Christian signed {{char}}
