It's already been said, but Beau and Diana. <3
Diana is snooty and Beau is lazy, so I can imagine Beau having a crush on Diana but worrying that she's too good for him.
Because Diana is snooty I can imagine her trying not to fall for Beau because he's such a ditzy lazy, but soon she can't deny how adorable he is! :]
Sydney & Eugene are definitely an item in my town, they suit each other so well.. They're always together, talking to one another, sending gifts to each other.. They're just so sweet
I also think Phil & Phoebe are a great couple, they suit each other so well, they both have fiery personalities, and while Phil may sometimes flirt with other ladies, Phoebe's there to keep him in check
