really? i heard it was random who asks to leave.That is how it works. The higher your friendship is, the less likely they are to ask. It's a pretty subtle difference, which is why you're probably rolling villagers who like you a lot, but it is there.
On the topic of the thread, I would really dislike the ability to ask Isabelle to kick someone out. It would just feel... wrong. It's one thing to lock it behind a paywall since scanning physical merch into the game is already a bit 4th-wall-breaky anyway. But having total control like that just doesn't feel like Animal Crossing to me.
i find the ones i have highest friendship are usually the ones asking to leave.
the only villager i have atm who gave me their photo is tia and she's asking the most.
