Warm But Tainted Blood (Drarry)

When Draco is attacked by a dragon and none other than Harry Potter comes to his rescue, flame is not the only heat source he is feeling.

Draco does increasingly reckless things to get Harry's attention, and in turn, the warmth he feels whenever he does. Draco has unfortunate luck, and after Harry saves his sorry ass multiple times and lots of begging, Harry finally agreed to be his friend.

There is a certain professor who disagrees with their friendship, and the lengths he will go to deconstruct it become more and more malicious as time goes on. That, along with a new seemingly unsolvable mystery every year(such as the Dragon Epidemic, and the Santa Claus Shooting), makes their friendship very difficult to maintain.

Draco knows he should stop- that hanging around with Harry is nothing less than dangerous, but he cannot find it in himself to stop seeking the warm but tainted blood.
