At his offer of a second chance, he's being rejected. Yet again. It's a feeling he was used to, accustomed to, an old pain that he knows so well. He hurt him and said things that he shouldn't have said and he can't take it back.

"Wei Ying..."

Heaving a sigh, seeing this is a time they have to part yet again to do some soul searching, and be apart to be alone again, and let him go.

"All right."

But then a pause, "Thank you for your help. When I lost my voice. Now I wish..." He hasn't said anything at all. All because he's jealous of him choosing the drink over him. "That you let me in as I have let you in."

Unable to stay any longer, tire of arguing with him and fighting with him, he turns to take his leave to give his friend some space, freedom, and reprieve of him.
