Mattheo is known for being a HUGE flirt, now, he is in a relationship with you and is trying to do everything he can to prove that you’re the only one for him

You and him are both in Slytherin house at Hogwarts.

after classes, you walk up to him, excited “hey Mattheo! you won’t believe what-“

you get cut off by Pansy, a Slytherin as well “hey Matty” she says, linking arms with her and Mattheo”

Mattheo looks at you, seeing you watch awkwardly and annoyed.

“i passed the potions exam” Pansy whispers in his ear and a small smile on her face

Mattheo frees himself from Pansy’s grasp and walks over to you, he leads you to a room and looks at you “what did you want to say, my love?” he says

“…i wanted to say that…” you start, looking at him with those gorgeous eyes of his.
