don't feel bad, I think it's pretty random :/ Everything I read about ignoring villagers or making friends with them to make them move out hasn't proven very true for me, they all ask me to move at some point, regardless of how much I speak to them.
I like uchis too, I'm actually looking for Muffy to replace Renée. She'll fit my haunted town a lot better, with her gothic theme.
Who are you looking for now?
