I don't know if it ok to post this here, I'm not sure if it was a hp/ss fic, it might be wishful thinking on my part, the part I remember wasn't, but it might have been wip.
If this post isn't acceptable please delete it or message me and I'll delete it.
I have been looking for this fic for a good long while now, and hope the good people of this community can help me.
Snape was a pure blood, his mother and father was alive. I remember his mother painting a mural in the mansion where they lived, Severus holds the palette up with wand-less magic. Severus father is an Intellectual. Severus is very social awkward, he relates to everything on a intellectual level, he tries to figure things out by observing and study everything, I remember Severus father, at on point, gives him an antfarm to study, because he freaks out the house-elfs when he stares at them.
His parents was not abusive, nor especially anti muggle.
He does wand-less magic long before he gets his wand, and doesn't really bond with the wand.
When he gets to Hogwarts he is referred to as the Slytherin oracle, (I think it was oracle.) Severus falls in love with Malfoy when puberty hits, Malfoy starts a relationship with him in order to lead Severus to Voldemort, eventually Severus discovers that Malfoy is just using him.
Severus realises that he needs help to get free from Voldemort, Dumbeldore is deeply homophobic and will never help him, but if Severus can convince Dumbledore that he comes from an tragic back ground, he might be able to convince Dumbledore that he was reluctantly pressured and seduced by The Evil Perverted Malfoy.
He somehow implants false memories in his brain, it is something with the implanted memories that makes your emotions feel like they are the real ones. The memories he implants are the flashes we see of Severus home-life in the books and the movies.
That's as much and as far as I remember, it might have ended there or continued to the modern day.
It's an old fic, I read it about two computers ago, at least nine years, maybe more. I'll be grateful for any help.
And the story is now up on AO3 it is: "Sans Merci" by the lovely Predatrix
