Lan Wangji and Wei Wuxian were out on a mission to exorcise a spirit. This one had all sorts of stories attached to it, however they all lead to the same conclusion. If one was cursed by the spirit they would turn into what their lover found least desirable. Apparently the curse worked for three days and then it was over however some said they could not look at their partners those days due to how much their apperace displeased them. Some even said they could not look at their lover the same way after that.
So inevitably Wei Wuxian managed to get himself cursed. Of course, they both panicked until they were sure Wei Wuxian was alright. However, the way Lan Wangji looked at him wasn't filled with disgust or anger. Rather it was shame, Lan Wangji was ashamed. Wei Wuxian looked around the room, setting on a puddle of water. There he saw himself, his own face, not Mo Xuanyu's but more feminine, dolled up in make-up. Then he felt the weight on his chest...
Out of all the things he'd have thought Lan Wangji would desire the least, this would be his last. He didn't like Wei Wuxian being a woman.
"Lan Zhan..." Wei Wuxian whispered in stunned shock as he turned back to look at his husband whom was fidgeting uncomfortably.
