Silent Guilt

KO doesn't know any way to cope with how he feels, so he does the only thing he think will work and tries to hide it. But it's hard to hide an injury from friends and family who care about you.

(Also, slight AU where KO and TKO didn't merge, they just came to an understanding instead. Plus, I'm posting this by itself as a oneshot instead of adding to my oneshot collection cause no one wants to surf through other fandoms to get to the one fanfic they want)
