Recs for reverse fake relationship, basically
Hello everyone! I would be very happy if anyone has recs for fics where it's basically like a reverse fake relationship--Character A tells their friends, coworkers, etc. about their boyfriend/husband/partner, etc. (Character B) and no one believes them and thinks they're making them up until they finally meet Character B and everyone's shocked that they actually exist. Preferably Merthur, but I'm open to other pairings :)
Thank you!
