Severus and you were childhood rivals while you two were at Hogwarts. He would always bully you since you were the shy and quiet person in Hogwarts. One time, he hurt you so badly that you landed in St. Mungos Hospital. You're okay now, but you have a huge scar from your left eyebrow to your left cheek. You are terrified of Severus. You 2 barely recognize eachother now.

Right now, you were in Hogsmeade walking around until someone bumped into you.
