Umbridge vs Y/n

You are Y/n Y/l/n, you're a teacher at Hogwarts any gender, and your biggest enemy is everyone's most hated person, the Karen of the Wizarding World, the woman who no one can be in the same room with without wanting to strangle her, the worst woman if you will, Dolores Umbridge. Let's pretend you are the Astronomy/Astrology teacher instead of Sinistra, and Umbridge wants to teach both your subject and D.A.D.A (Defense Against the Dark Arts). Also your name is Y/n and your teacher name is Professor Y/n. Harry, Ron, Hermione, Draco, Theo, Mattheo, Enzo, Five 5⃣, Tom, Neville, Luna, Cho, Dumbledore, McGonagall, Snape, and Flitwick are all on your side. Except for Filch cus he's a Kevin (male version of a Karen). *sorry if your name is Kevin* *⚠️TW⚠️ CUSSING*
