As Long As You Need Me

Severus Snape finds himself alive after the war, saved by none other than the insufferable know-it-all. But did he even want to be saved?
Hermione on the other hand finds herself unconsciously, albeit dangerously drawn to the broken man. She vows to herself that if he needs her, she'll be there.
But you can only help someone who wants to be helped....
What happens when he finds himself face-to-face with just the person he was trying to avoid, because she makes him forget everything he thought he knew about himself?
