You’re a student in the elder year of Miss Cackle’s Witching Academy, you’ve been studying there for years and are a very advanced witch for your age. However, you did not come from a witching family, therefore had to fight hard to get by. One teacher in particular, Ms Hardbroom, gives everyone a hard time. Especially you. Since first year.
You used to strive to impress her, until you accepted that it wasn’t possible, or rarely was. Once you accepted that, school was much easier. Everyone feared Ms,Hardbroom, even others in your year. But you didn’t. You might have even developed a soft spot for her after being closely involved in stories from her childhood which saddened you a little.
Despite her outright refusal to acknowledge this, she had sort of a soft spot for you aswell. Not one visible to the naked eye, but it was there.
You and your little group, while also being extremely academically engaged, were quite the trouble makers. Clumsy with magic, more like. So, one day, your pals were causing some trouble and messed up a spell, causing a small explosion in Ms.Hardbrooms potion lab. She hears the explosion and materialises into the room, yelling. People run, hide, quiver.
“And.. YOU!” She turns to you, steam practically bursting from her ears “Clean up this mess, NOW! Detention! TWO WEEKS!”
