I have two.
Nate because he's my bby omg. He was in my GC town and I thought he was
perfect. I think the lazy personality is adorable. I would stop playing for months on end, TT
years and he was the one villager that never moved. Also, because of how lacking the storage in the GC version was, I put a little "mall" of about 25-30 shirts in the acre in front of his house since I knew that I'd be going there daily

When I decided to restart the town that I'd had since the release date a little while back, I wanted to reset until I got Nate, but I ended up settling for a map that I liked instead. My sixth villager ended up being Nate. I couldn't stop smiling when that happened.
And Freckles who is another favorite from GC. Peppy is my favorite of the female personalities. I might be the only one thinks so, but I find her design to be super cute as well. I was able to recruit her to my first town as the tenth villager then did the same today with my new village c:
They're really the only two characters that I consider to be ~dreamies~ of mine, so I'm happy that they've both moved into my town.
