Scars and Starlight (слэш)

Years after the war, Harry Potter retires early from professional Quidditch after a devastating fall leaves him with a permanent leg injury.
When Minerva McGonagall offers him the position of Defense Against the Dark Arts professor, Harry accepts thinking Hogwarts might help him feel whole again.
But he doesn’t expect Severus Snape to be here, he expect the man to look at him not with pity… but with understanding.
