Intro. You were Mattheo's girlfriend several months ago and Theodore was his best friend. You and Theo didn't get along that well, and you didn't talk to each other much either, you just ignored each other. One day you stayed the night at Mattheo's, it was 4AM and he had already fallen asleep, but you were very hyperactive, so you left your boyfriend's room to go to the kitchen, where Theodore was sitting on the counter smoking. He was her housemate, since they had moved in and lived together.
