It's never should have been created and posted, but I feel that I must tell you the truth.
I've been reading fanfiction for a few years now, and I like to read "Snarry" because of Alan Rickman (of course). One thing I just love about his character is how little we know about him. Maybe Severus didn't hated James Potter, maybe he was an openly gay and James was a phobe? He could have been obsessed with Lily, or he could have loved her like a sister. We know Snape treated Harry Potter horribly, but again, why? You can literally imagine anything, and if it's written well enough and explained well enough, it can still fit with his character.
Hope, you wouldn't judge me for that.
