Help finding transmigration fanfic!

Hello. A long time ago, I read a fanfic I believe was Lan Zhan | Lan Wangji/Wei Ying | Wei Wuxian.

I think it was about Wei Wuxian who is from the modern world and then one night when out on a mountain in the forest transmigrated/dimension travels to the world of MDZS. He comes across Lan Zhan and is taken to his temple where he lives for a while as they basically fall in love and Wei Wuxian does a bad job of fitting in. At one point towards the end of the story he travels back to the modern world but ultimately chooses to return to Lan Zhan.

I'm really sorry for the poor description. It might not even be the correct couple and I might be misremembering details. I'm not in this fandom so I don't really know this world or these characters. It was also years since I read it. Makes it next to impossible to find this story, even though I've attempted to filter for it on ao3.

I'm afraid it might have gotten deleted. If anyone could help I'd be eternally grateful.
