“So let me get this straight, you’re going to ask Lan Wangji to be your boyfriend for Jin Ling’s birthday party because?...” he trailed off, and Wei Wuxian rubs his forehead tenderly, ignoring the rude glares coming from across the coffee shop. This would be the third time he’s been almost kicked out (not that he’s counting).Nodding along, “because I need your mother to stop bothering so much about dating.” then pauses, “and I thought it would be fun.” he adds slyly. Jiang Cheng’s eyes roll greatly, possibly to the ends of the earth to Wei Wuxian’s explanation.“You want Lan Wangji to pretend to be your boyfriend to impress my parents, then dump him after less than twenty-four hours.” Jiang Cheng says flatly.(Or: Wei Wuxian needs a favor, and asks Lan Wangji. But it's different from the others and something unexpected comes out of it, and a whole lot of suffering and pining comes with it)
