Here's a comprehensive Villager Move-Out guide:

Here's the thing though...
The less friendship points they have, the higher the chance of them moving out. It may seem that those with higher friendships are more likely to move out. But that's because the game
takes the average friendship points you have with ALL villagers. So, it's a bit of a dilemma. So I guess in the end, you might need to befriend them after all, so everyone has an even chance of asking to move out.
Also, take note a villager cannot ask to leave if:
- they are the last villager to move in
- they are the last one who asked to move out, but you said no
- they have a birthday coming up within 7 days
- the villager is in the process of relocating
If Ed and Bruce is one of the above, they will not ask to leave. Your best option is to kick them by replacing them with an amiibo, or a camper.
