he's not forgiving him, he's trying to escape his past trauma with his ex by hurting himself with the same pattern as before
In that way vercion might view it as sunwon forgiving him cause in the first place he didn’t even know the thing he did
He might be finding out next chapter since he realized at the end of this one that Sunwon's looking at him with the same level of fear in his eyes as he did with his ex.
I hope so
Wth sunwon i don’t get it after all the shit vercion did to him he still wants him to f him dude thats why his ex was abusive towards him cause of how he forgives and move on
