I've been wanting to write a Luisa x OC(Jeronimo Perez specifically, I'll give his profile in a later post) and I think I've landed on a proper idea of how they got together and what to actually call the fanfic:
With Casita's fall, a lot of parts of the community's workings changed. This included non-emergency requests for help from half the family having to be given beforehand through letters. Lucky for them, some of the members of the large refugee group that came during Casita's rebuilding knew how to run a postal service.
People seemed to be getting a bit too excited with the service though, resulting in the postal office requesting Luisa's help with heavier deliveries a lot.
So what does Alma do?
Get Luisa officially employed there part-time of course!
And what does Luisa do in response?
Befriend the mailboy of course!
Certainly romance shall not appear, will it?
