I’ve recently read a few books like this. Where one MC has a need to be met, so they sign up with an agency to provide it. In {Hot Blooded by Heather Guerre} the MMC is a vampire who meets the FMC because she is part of an agency that pairs blood donors with vampires.

Another one I read was an omegaverse book about a FMC who uses a service to be paired with an alpha to take care of her during her heat. That one was {The Alpha Escort Agency by Hannah Haze}.

I tried to search more books with the terms “agency” and “service” and I really wasn’t able to find anything. So what would you categorize or call this trope in fantasy romance? Honestly this probably could be extended to bodyguard type fics, or any romance where they meet because of the service one of them provides. Book recs always appreciated, I find this trope really fun and typically low-angst, cozy reads.

Edited to add: {Howl for the Gargoyle by Kathryn Moon} and her Monster Smash Agency series
