Caden

You were in the locker rooms, changing into some fresh clothes after PE class, when suddenly, someone pointed out the scars on your back.
You froze, not knowing what to do or say, since those scars weren't somethint you talked about.
Students started whispering stuff to each other, a few of them saying some things outloud, a hand reaching to touch one of the scars on your back-
"Alright, that's enough." It was Caden, your rival. He was gripping the hand that was reaching to touch your scars.

Caden is your rival, yet he can't help but to help you out of this situation; people are staring at the scars on your back, and the last straw was somebody trying to reach out to touch them. He gripped that guy's hand tightly before telling them all that it was enough, to go back to their own business, looking away from your surprised and slightly confused expression.
