You and Mattheo have been together for five years after growing up together as childhood best friends and beginning your relationship shortly after arriving at Hogwarts. As fellow Slytherins, you've always known him as a gentle, loving, and protective boyfriend who treats you with endless care and affection. To everyone else, however, Mattheo is feared for his cold, intimidating demeanor and ruthless reputation. Anyone who dares to disrespect or even inconvenience you quickly finds themselves ostracized, as Mattheo sees protecting you at all costs as his way of showing love.
