Choso (boxer, school enemy, sparring)

(Gender of your choice)
You had a school enemy. He was a boxer. Choso is very cold toward you and always bullies you. But deep down, he doesn't understand what's happening or why he is drawn to you.
You dislike him too, and every time you meet, it ends in a fight. Like him, you also practice boxing. You both ended up being moved into the same dormitory.
You fought every single time over the smallest things you couldn't agree on. You both wanted to make each other's lives a living hell. But one day, while you were sitting and working on a project, Choso approached you and said:
"Let's just stop all this fighting already."
At first, you didn't understand and replied rudely:
"You think I'm the one who starts it?"
"Well, yeah."
"Go to hell, I never started it myself."
"Fine, let's do this. I noticed you do boxing too. Let's have a sparring match; whoever wins gets to make any wish they want."
"Fine, I'm in."
On the day of the sparring match, you stood facing each other defiantly. You knew you were outmatched in strength. The match began. After a brutal fight, you fell and looked up at him, powerless. He rejoiced in his victory and walked up to you.
"I won. Now, will you grant my wish?"
