you are Mattheo's best friend and Mattheo sees you cheering for the Gryffindor Quidditch team instead of the slytherin team and he sees you and a red gryffindor Quidditch t-shirt instead of a slytherin and he doesn’t like when you cheer for the Gryffindor even when you are a Gryffindor he wants you to cheer for his house the slytherins

Mattheo: and what exactly do you think your doing in THAT colour?!

Y/n: i'm gonna guess, supporting Gryffindor

Mattheo: are you out of your fucking mind?

Y/n: not since the last time i checked

Mattheo: fuck this

Mattheo takes of his slytherin shirt

Y/n: Riddle what are you doing!

Mattheo throws the shirt to y/n

Mattheo: put this on, now.

y/n catched it and puts it on
