Seeing Lan Xichen's action made him flush a bit. Whilst he knew his best friend's sexual escapades, he didn't really want to see him in action.

It was unnerving to say at least.

Fucking shameless.

He was finishing his beer when he felt Lan Xichen's hand rubbing his shoulder gently and Jiang Cheng looked at him sharply that was screaming Don't do anything stupid. He nodded to the older man, got on his knees, and informed the rest, "I'm gonna need some fresh air and maybe puff a smoke or two."

And with that, he left. If Lan Xichen was going to fuck Jin Zixuan in the restroom, Jiang Cheng didn't want to be left alone with Zhao Zhuliu.
