If you mean which characters each player thinks is the most adorable, my answer is: Hamphrey and Molly.
In regards to Hamphrey, I love how he's a cranky villager always wearing a modest smile, and how he acts tough but gets embarrassed if you say he's nice (something along the lines, "You... you think I'm nice? Not so loud; I have a reputation to keep!"), and when overwhelmingly happy over a kindness can't help blurting out "You're just... so nice!" Heh. Stuff like that.
