Janitor and Juliet
From the very start, theirs was a forbidden love.
She was a beautiful witch from the upper society. With pretty brown hair as silky as the velvet bow that rested on it and a melodious voice, clothed in heavenly looking pink jumpers and green tweed.
He was a lowly squib janitor, with shabby clothes and a worn face, and rough skin on his hands.
She bossed him around like she was expected to, and he always did as asked, thinking that maybe, maybe someday, they could break these constraints and truly love one another.
Day after day, looking into those pretty, controlling eyes, he would give her a small smile and do whatever task she had set for him. Be it just regular cleaning, nailing up rule after rule, or hunting down troublemakers.
He never even got a word of thanks.
But he knew, even after she had been sent off to Azkaban, that forbidden as it was, they loved one another deeply.
And besides, Filch thinks, pushing his broom.
They would always have their shared love of cats.
