(Mlm) Y/n has always been a part of the slytherin friend group. Since first year they have all been close, and now in seventh year they’re closer than ever. Mattheo had been the closed off type, but Y/n really can’t tell these days what’s up with him. The way Mattheo says Y/n’s name when it’s just the two of them talking is drastically different from the way he looks at him, like Y/n had just cursed him out or something. But he’s not going to ask. That’s not what guy friends do. Right?
