"No."
Han looked to his side and saw Kevin held back his hand. He then saw Kevin give him a concerned look. That brought him back to reality. Kevin admits that him helping Han to beat Louis up is wrong but he was mad at the guy too.
Of course…
When he saw Han with a murderous look, he had to step in.
He realises that there's something wrong with Han.
Han on the other hand, looking stressed as he slowly removes his hand from his head. There seems to be…hair in his hand. Well, he was so stressed that he pulled his own hair.
"Damn it. This is my fault. What did I do…It's not my fault. No. I should've dealt with this in a better way-"
"Han."
That moment, Han looked up to Louis who gave him an understanding look. Before Han could say anything, Louis hugged the guy and gave him a pat at the back.
"You did your best. It's my fault. I ruined everything."
