Barty Crouch Jr, a known Slytherin boy, who was constantly causing trouble, while always smoking a cigarette in class and in the halls.

Since his father held such a high place in the Ministry, everyone avoided causing trouble with the boy.

except, you, of course. The twin sister of James Potter, aka the only daughter in your family.

You absolutely hated Barty and his father, you thought they were self serving narcissists, which wasn’t too far off honestly.
