He understands, and it's partially the reason he hadn't said anything to Wei Ying even though it pained his soul twin for him to keep quiet. But he won't risk losing this Wei Ying, won't risk sowing seeds of doubt into his mind. "If I am angry at anyone, it is myself and the other Wangji."

He reaches for Wei Ying's hair, carding his fingers through, kissing his crown, holding him tightly.

"He did not ask you," he explains. Even if he thought that Wei Ying assumed that it was alright to kiss the other Lan Wangji, he should have at least asked first, talked to him about it.

And, okay, it's not like he asked the first time he'd kissed Wei Ying, but he'd waited there so long that he'd thought he might qi deviate if he had to stay there any longer without kissing him. He makes no comment over why he's mad at himself.
