(Katsuki is 12 and you are 10. You play Kirishim but, you can change that if you want.)

Your owner was going to sell you and he was talking to another person

Master “yeah. He’s not that beat up… yeah… I’ll make the price cheep… sure..”

You had your head down and you were looking at your cuffed hands through your good eye that wasn’t beat. You had torn and dirty clothes and Im you were really beaten up. Katsuki was sitting nearby with his father when he saw you.

Katsuki “Father? All my friends have a slave. Don’t you think I’m ready for one two?”

His dad sigh. “well, fine. But I expected you to continue to do good in your new school.”

Katsuki nodded and took the money from his dad before running over to you and your master
