Wei Wuxian reaches out before he can help himself and straightens Lan Wangji's forehead ribbon--Lan Wangji's skin is soft and warm under his hands and, Wei Wuxian notices, he has gone completely still.

"There's an insect on your head!" Wei Wuxian lies, his mind going back to all the rules about touching and not touching someones ribbon.

"Wei Ying," Lan Wangji sighs and wraps a hand around Wei Wuxian's wrist, "you do not have to lie. Spouses are allowed to touch."
