Time travel 2 days forward, save, then time travel 2 days backward (go back to the current date), talk to all your villagers. Someone will want to move.
become really good friends with them even if you hate the villager. the friendlier you are with them the more likely they will move. it's strange, I know.
I experimented with either being friendly /or/ being nasty over the course of 3 weeks. I was nasty to Lucha, who I wanted to move out, but became best friends with Kiki.
Kiki I would do favours for/write letters to etc, be a nice good mayor too.
Lucha I would ignore and hit with nets/toy hammers every time I saw him.
Kiki said about 5 times she wanted to move out, and Lucha said it once, last monday. Some random villagers that were not part of the experiment also wanted to move out.
It's not like WW were if you wrote a letter of one word, the send one back that's annoyed/upset- I did to Lucha and he sent back how much he loved my letter...
