You're walking into the Slytherin common room because you found Mattheo an anniversary gift. As you're approaching the dormitory area you hear him and Draco arguing, or rather contemplating and reasoning.

"Dude, it's been 3 months. You won the bet. Now break up with her" you hear Draco yell at Mattheo. He's quiet. But maybe the best thing is a joke, right? Your mind is spinning, you don't know what's going on. Does Mattheo love you?

"How can I tell her she's just a bet?"
