Harry Potter: Partners in Crime

You chop off hands, and I cut out tongues; You make poison, and I add the ingredients; You want to kill someone, and I'll bury the body; You pretend to be loyal to the Dark Lord, while I feign devotion to the headmaster. You live on for the sake of the person you love most. I, indeed, cling to life here for the sake of a promise. You and I were classmates once, comrades later, and colleagues now. And we're both damned souls. People say we're partners in crime, but I think we're more like a perfectly matched pair. Severus Snape, we've known each other for twenty-seven years. You can't do without me, can you? (Professor Snape x an original female protagonist. She is absolutely no innocent white lotus, so rest assured: she's ruthless and merciless. Unlike ordinary fanfiction, this story won't change the ending of the original Harry Potter series. In other words, the professor will still die, and the heroine will ultimately go to hell. This story simply wants the professor to be a little less lonely. Partners in crime: a story about villains. Written purely for fun, not contracted or paid.)
