u/undoubtfulness

I read this on Ao3 within the past year and cannot seem to find it again. I tried finding it with tags, but wasn't lucky/specific enough since maybe my clues were not official tags.

Madame Yu finds Wei Wuxian's pregnancy test and uses it as the perfect chance to get rid of Wei Wuxian for good. Tells him that the Lans reject him and the baby, tells the Lans that he ran away with his new bf. Madame Yu basically sends him on the next flight out of the country, and takes his cell (to impersonate him for awhile).

Modern AU starts in China ends in New York?
Alpha x Alpha Wangxian (no bitching)
A-Yuan is their baby
Wei Wuxian wears glasses post-partum
Lan Qiren finds them due to the University Wei Wuxian works at is an affiliate to Gusu Lan
Wei Wuxian tells A-Yuan about Lan Wangji by saying he's an astronaut lost in the stars and that's why they haven't met.

It's completed and listed as so.

Thank you for your help!
