Huaisang easily lets Jiang Cheng lead him once he's agreed to the offer. He hadn't totally expected the other to agree to it but... he's happy about it. He cares about Jiang Cheng, he always had and he'd wished their friendship hadn't been forgotten in the midst of all the trouble in their lives. They could have helped each other more... but then again maybe things wouldn't have ever been made right in Huaisang's mind. Maybe he would have let go of his anger if he had had anyone at all to trust.

When they get to the other's room, Huaisang licks his lips and he waits to see exactly what Jiang Cheng does or says before he makes a move.
