*blushes*
Mr. Darcy, from Pride and Prejudice, definitely. (He's indescribably amazing).
Laurie, from Little Women, despite his immaturity. (How could Jo refuse him? How?!)
Draco Malfoy, from Harry Potter, because he's a bad-ass Slytherin. (Okay, so maybe I didn't fall in love with him, but I think he's really sexy. That counts for something, right?)
ANDDDDDD, last but not least:
Marius, from Les Miserables, because he's so sweet and devoted. (I would totally die for him like Eponine did! Isn't that sad?)

Nico Di'Angelo for the Percy Jackson series, Owen from The Protector of the Small series (He's a minor character people! XD), And Artemis Fowl from the Artemis Fowl series!

I've got a couple, but the first one I'm particularly embarassed about:

- I had a short phase, when I first purchased Sandry's Book, when I had a huge crush on Briar. I think it still sorta lingers a bit. What's embarassing about this is that I was 15 when I first purchased the book (I'm now 19)... and Circle Briar is 13.

- From the first book, I had a crush on Harry Potter, all the way up to the seventh, and it's still there. I had a soft spot for Neville too. An unusual one is Draco... I hated him until I started watching the movies, at which point I started to like him because I think Tom Felton is hot. <3 And I think I might've had a thing for Sirius, too... I don't know why.

-And then there was Piggy from The Lord of the Flies... I have a soft spot for geeks. :) (I'm kind of a geek, myself.)

- I also have a thing for sensitive guys... which is why I will now proclaim my love for Kaname Kuran of Vampire Knight and Night Tenjou from Absolute Boyfriend. (Not sure if those two count in this thread, but I'm confessing anyway.)

- Speaking of vampires, even though I've only read the first volume of the manga verson, I have a thing for Alexander Sterling from Vampire Kisses.

Recently I am falling in love with Richard from the Sword of Truth Series all over again.
It's bad.
