The boy in the last compartment

AU OOC EWE. After the war, a lonely Slytherin returns to Hogwarts because he has no choice, he is on probation. He's sure everyone would hate him and he will be alone and miserable. Or maybe a Gryffindor girl will have the courage to offer a helping hand? Mature content for language and possible sexual situations. An unusual pairing, Dramione and a hint of Hansy.
