Snape is not a Snape(Jeverus)

when Severus Snape is in his first year he gets to find his parents. It turns out he is not a Snape, but who IS he then.
There will be themes like abuse but that will only be lightly themed, it will be light-minded. There will be swearing later in the story, but we all do it sooo...

I'm completely bad at writing descriptions, so sorry If it's not very good.
