I've seen a lot of fics on this meme (and otherwise) show Marcone to covet/love Harry so deeply, almost with a single-minded ferocity from the very beginning, and be ready to do just about anything for him.

What about a reversal of this - how about Harry being that mindlessly (?) in lust/love with Marcone from the first time they meet?

I have NO idea how something like this would work, which is why I'm throwing it out in the meme. Maybe someone has an idea?
