I made everyone call Diana "Princess," and I told someone to call Stella "Sunshine," but if they offer to change it again I'll probably just tell them to call her Stella. Angelina's nickname will be Angie, and when I'm done with plot resetting and make Keiran, I likely won't give him a nickname, but I might tell villagers to call him something similar like Keirnan because Keiran is supposed to be so quiet no one ever hears his name right.
Everyone calls me Ms S courtesy of Francine. I like it. Although Hamlet still calls me the name he suggested, muscles, which made me chuckle as its not true at all!
My first nickname was "J Bear", which I believe Beau started. It's cute and I've actually grown attached to it, but now Chief decided to change it to "kid". c: I like it!
