Y/N and Mattheo Riddle have been inseparable since their first year at Hogwarts, growing up as the closest pair in a tight-knit Slytherin friend group alongside the other boys and girls. While Mattheo is usually guarded, sarcastic, and impossible to read, Y/N is the one person who sees the real him—the boy who can laugh freely, let his guard down, and simply be himself. But lately, something between them has started to change. Mattheo’s usual teasing has become more lingering looks, deliberate touches, and comments that sound suspiciously like flirting. He insists he’s only joking, yet his feelings for Y/N are becoming harder to hide. As their friends begin noticing the tension between them, Y/N starts wondering whether their friendship is still just friendship—or if somewhere along the way, Mattheo Riddle has fallen for his best friend.
