“I’ll help,” Lan Wangji says.
“Hey, Lan Zhan...” Wei Wuxian unfolds his leg and gives his foot a playful kick. “I told you to think about it! This means I’d be here for a long time, taking up your time, your space, your peace. And I can’t pay you! I have nothing of worth to give. It isn’t as simple as-”
“I’ll do it,” he says again, more forcefully this time. “You don’t have to give me anything.”
Wei Wuxian looks away, hiding a small smile. Doesn’t he know Lan Wangji would do anything for him, by now? Doesn’t he understand that he holds Lan Wangji’s life in his hands?

POST-CQL Wei Wuxian comes back to the Cloud Recesses to ask for Lan Wangji's help with his new golden core.
Together, they learn how to communicate, how to ask for things, and how to touch each other.
Their relationship develops in between quiet dinners in the Jingshi, meditation sessions, core training and a lot of Lan Juniors speculation on whether or not they're actually together yet.
