I don't wanna talk about it (слэш)

Draco is supposed to kill Dumbledore and he's failing miserably at it. So much that he finds himself spending time crying in the bathroom. And Potter couldn't mind his own business if his life depended on it.
Basically, this is my take on the Sectumsempra scene and how it could have turned out better. Drarry doesn't occur until quite late in the story.
