It was an accident, It was just an innocent accident. How could Gohn make it up to him? He can’t, does he? He hates himself at the moment for what he have done.
Although it is temporary - Hansol couldn’t look at him in the eyes anymore. But he can’t stay mad at him for long… not since he has those suppressed feelings of his… He wants to be mad, he wants to slap him for breaking his hand, he wants to scream at him that it screwed up their performances - but he knows he can’t.

“I don’t care how much you’d apologize… I hate you.” He lied to him, and to himself.
