Well, actually this one might be correct.  Yeah, I know, weird, but let's look at it logically...

In Half Blood Prince, Harry CAN'T stop thinking about Malfoy.  He even says so himself that he is getting "obsessed."  Hermione starts getting irritated about how much Harry is thinking about Draco (and not herself!!) and won't listen to Harry when he says that something is up with the ferret. 

Harry even snuck into Malfoy's train compartment to spy on him!  That's going a bit too far, if you ask me. 

And don't forget in the movie version of POA, where Harry and Malfoy stare at each other for about 30 seconds, making poor Ron feel uncomfortable... That was when Draco starts teasing Harry that he fainted from the Dementors.  

 

Draco later in a classroom even sends a love note to Harry!!

 

Annndddd in POA, Malfoy says that "The Dementors send their love, Potter!"

Whoa.  Did he say "LOVE?!" 

 

And in about a hundred other parts in the book series, Malfoy's attention is on Harry.  For instance, when they are dueling, here is what it says:

"For a split second, they looked into each other's eyes, then, at exactly the same time, both acted."

Ummmm yeah.  Why are they looking into each other's eyes?

Lastly, don't forget this line:

Harry: Malfoy knows.
Ron: You're going to take Malfoy's advice instead of ours?

 

Poor Ron yet again =(

 

But, IMO, it's Draco that is obsessed with Harry.  While Harry has his moments with Draco, Malfoy is the one always bringing them on.  *Almost* sweet in a way.... though Hermione might have to punch Malfoy again!
