Aww. It's so sweet and cute but no, it isn't the one I'm looking for.

I remember that Draco had everything planned for the seduction, from rose petals on the sheets to sexy attire... only to ruin the sexiness of it all by sneezing in between his 'sexy talk' to get Harry to undress him. Something about the material of the sexy clothes he had on that clashes horribly with his feverish flushed skin, I think. Um, and when Harry tells him, he loves him despite the not-going-to-get-any part, it was the first time Harry says the words as their relationship (at first) was based on only sex. This, I'm pretty sure because I remember Harry drawing out the 'I love you' confession (due to nerves) by listing out every bad habit Draco has and saying he loves them regardless.

Still, thanks for the rec!
