Oooo a Harvest Moon RP, interesting! I haven't played a lot of Harvest Moon, but it was fun in the brief introduction to the series I had with it. I did love Stardew Valley though and I've heard they're similar. Anyway, I haven't had a lot of roleplays on this forum, but this sounds so cool and I'd like to try if you'd have me.
Out of the list, I'm coming up with ideas for a fisherman or innkeeper, maybe a cafe owner. Gotta keep options open and it helps to have alternatives. Honestly though, I could roll with anything.
