You were a witch. it’s pretty obvious though since you go to hogwarts. Your speciality was potion making, and all the students could that to their advantage.

one day some of your friends dared you make make a love potion. you did easily, and you were walking to go show them.

but you bumped into Regulus, your enemy which made the potion spill on you! Regulus didn’t know what it was, so when you started staring at him in awe, he was insanely confused, and a bit annoyed with you.
