Choso (boxer, school enemy, sparring)

(gender of choice)
You had a school enemy. He was a boxer. Choso is very cold towards you and always makes fun of you. But deep down, he doesn't understand what's going on and why he wants to be with you.
You don't like him either; you started fights every time. You, like him, were into boxing. You were moved into the same dorm with him.
You always fought over little things you disagreed on. You always wanted to make each other's lives hell. But one day, you were sitting and working on a project. Choso came up to you and said.
-Let's stop all this fighting already.
You didn't understand at first and said.

• Do you think I'm starting this? They answered rudely.
  -Well, yes.
  -Fuck you, I never started it myself.
  -Okay, let's do it this way. I noticed you box too. Let's have a sparring match, and whoever wins can make any wish.
  -Okay, I agree.
  On sparring day, you faced each other defiantly. You knew you were inferior in strength. The sparring began. After some brutal sparring, you fell and looked at him helplessly. He rejoiced in his victory and approached you.
  -I won, will you fulfill my wish now?
