Obliviate

Summary
Harry survived impossible odds all his life: his hateful relatives, their abrupt decision to kick him out, and then the years he spent staying alive on the streets of London.
Situations weren't impossible, not when Harry had the one thing that kept him safe and made him special: magic.
And then getting to go to school filled with other magic kids? Getting a gang of his very own? Finding out that he was famous and getting to learn more and more magic?
Life was brill.
Life was not so 'brill' for Severus Snape who saw a small boy covered in scars, stuttering when he spoke, and seemed to be filled with unresolved trauma. The boy he vowed to keep safe had a true knack for chaos, a knack that even Severus could hardly contain.
Welcome… to Year One.
