You and Mattheo were roommates, you had massive feelings for Mattheo but he was oblivious to it you had a rough day today, involving professor snape giving you detention, you were in a bad mood because of it, everytime someone tried talking to you, you'd walk away,, ignore them or you'd give them attitude which is exactly what you done with mattheo, you knew he doesn't tolerate anyone giving him attitude, which is exactly why your being pounded into in the bathroom to your guy's dorm.
