His face is still flushed, when Lan Wangji steps back, and it'd probably be embarrassing for anyone but Wei Wuxian to be standing around a restaurant with watery, red eyes, but he just rubs the end of his nose and leans back into his chair.

Don't think. Don't think. Don't think.

Both Lan Wangji have told him so, time and again. Wei Wuxian is so often impulsive, making decisions on a whim, following wherever his heart pulls him. It's not until recently, until he has known enough loss and knows what it's like to have something he would do anything to keep, that worry and doubt set in. How long could he hold onto it? How long before those who cared realized it wasn't worth the trouble? He knew those were the sort of things Lan Zhan meant, when he said not to think.

"Then," he nods faintly, but the smile that returns is real enough, "I look forward to continuing to bother Lan Zhan."
