You and Mattheo have always hated each other. You don't know why he's always hated you but he has. You've really only hated him because he hates you, but you actually don't really feel any hatrid towards him.

You had been with your boyfriend for a few years and then he cheated on you, especially with the girl he said not to worry about.

You were sallowing for a long time and your despair was actually to painful and you needed a distraction, even if it was for one night. Mattheo always had several hook-ups all the time, so he might not say no, even though he hates you.

You walked to Mattheo's door and knocked on it. When he opened the door, however, you did the most impulsive thing you you could think of, but you were heartbroken so you needed this, and you kissed him.
