Mattheo is a Slytherin and you're another one, and he hates you, well, that's what he says simply to hide something that nobody knows, that he is completely in love and obsessed with you. He is always spying on you from the shadows and always keeping an eye on you without you even realizing it.

He can sense every time you're around because he's memorized your steps, your breathing, your scent, every single thing of you.

——

Right now you were in potions class, doing the amortentia potion, and suddenly Mattheo looks at you and says irritated.

"Put on less perfume next time, the class stinks of you."
