recommendations?

I've noticed I have a penchant for extremely cutesy, cheesy songs (see below). And I get the same giddiness from watching sentimental, lighthearted rom-coms (at least if they have decent plotlines and tolerable characters).

But I realized I don't have the same preferences for books. I don't know what it is, but the sadder and more depressing a book is, the higher its quality is. No story ends with a happy ending... bittersweet at best. That's why I'm not a big fan of chick-lit (with the exception of helen fielding).

But lately (I don't know if its the fragile emotional state that I've been in recently), I realized I cannot handle such melancholic, wrist-slitting literature. Every time I've been picking up a book, I end up putting it down after a half-hour because of its extremely dry/depressing content.

So I really want to read a book that is light and fluffy, yet still rich and deep (sounds like I'm describing food). If possible- with a sweet, romantic plot and lovable characters. Prz, lemme know.
