What's a cute song for a couple that fits this criteria?

One about a boy and a girl and they've been best friends for as long as they've known each other and they both had crushes on each other for about as long as they've known each other but neither of them said anything for a long time but then one of them confessed their love and they got together and now their closer than ever. I know that's kind of specific, but it doesn't have to fit exactly; just pretty close. :) Thanks in advance! :D
