A WangNingXian thing that I don’t see much but go feral for every time is Lan Wangji slowly progressing from having his extremely complicated tangle of emotions re: Their Song being the song WWX used to soothe Wen Ning, and apparently he doesn’t even realize it, and Wei Ying is Alive he’s alive he’s here he’s alive again and he’s playing Lan Wangji’s love song to him for his goddamn pet zombie—
Into being high key weird and tender horny about exactly that. Lan Wangji wrote the song that brought Wen Ning back from the brink. Wei Ying played it but Lan Wangji taught it to him. He wrote it for Wei Ying and then Wei Ying used it to save Wen Ning which means in a way that Lan Wangji saved Wen Ning. It’s THEIR song. It’s for all of them. Wen Ning starts humming wangxian quietly one night and Lan Wangji climbs over a table to bite the veins in his neck about it.
