MDZS/Untamed fan fiction
The sound of a badly played flute wafted through the mountain. Lan Wangji inwardly winced at the noise. The sound was eerie and out-of-tune. He tried to ignore it, as it really did offend his ears. The music stopped, then started again. It did this multiple times. He continued to try to ignore it, until a familiar melody reached his ears. His eyes widened as he recognized the tune being played. His entire body froze for a moment, believing that his ears were playing tricks on him. But no, it was, indeed, WangXian. There was only one other person who knew that song. Only one other person who could play that song, and who would play it on a flute.
Or in other words, what happened when Lan Wangji heard the flute playing WangXian on Dafan Mountain?
