For Severus Snape, after what happened at the end of Book 6 and you know what that is.
It is Christmas morning and Severus Snape brews a potion. He knows it will always end in success, unlike hoping that Potter will ever return his feelings. HP/SS
Post Book 7. Voldemort is dead and Harry goes back to Hogwarts to finish his last year of school. He gets along well with everyone else except one and not even his Firebolt can help. Or can it?
