A lot of things play on his face. He cycles through emotions from shocked to upset to jealous to upset again. "He... kissed you?" he asks, after a long pregnant pause, the only thing he says for a moment.

Because, if his Wei Ying were to have been the one to disappear - he would have been sad, but. He wouldn't have kissed the other one.

When he'd showed up in this hotel alone, the thought hadn't crossed his mind. And then Wei Ying showed up, and he'd told the other one - they had to set boundaries, that he wouldn't do anything that would possibly hurt his Wei Ying.

Yet, Lan Wangji - he'd agreed to the other Wei Ying, hadn't he? That he could see this one. He'd probably assumed they did things like kiss all the time. He takes a deep, heavily annoyed breath.
