1993
It had been twelve years since Remus Lupin's world had fallen apart. He had left his longtime, on-and-off partner, his three best friends had been brutally murdered, with his fourth best friend being the reason for it, and his 'nephew' of sorts had been torn out of his life.
Albus Dumbledore had, as per usual, given Remus a goal for the next year at the least, in hiring him as Hogwarts' Defence Against the Dark Arts professor. The only downside to this arrangement was that Remus would be forced to come face to face with the aforementioned longtime, on-and-off partner, Severus Snape.
I left my head around your heart
The two men had their first and only open conversation early on in Remus' stint at the school, when they had encountered each other while patrolling the corridors after dark. After muttering the cursory "Good evening Severus.", Remus was surprised to hear the other man answer him.
"You were right Remus."
"I'm sorry?"
"You were right, years ago. I let myself… become something terrible. Filled with hate, and mistrust, and lies. I can't apologize. But… I am trying to… to trust you, Remus. Even about Black."
With that, Severus left a shocked Remus to ponder the meaning of those words.

Why would you tear my world apart?
He could not believe it. Severus Snape could not believe it. He had managed to catch Sirius Black, the one living person he truly, mercilessly hated above all others, and he, Sirius, had escaped.
And what was worse, Remus, who Severus had grown to trust in spite of everything, had turned against him at the last, and sided with Black. Allowed Black to escape. Destroying any chance at justice that Severus had had.
And yet, after all these years, Severus Snape was still surprised at how much that betrayal hurt.
Always, always, always, always
