They met in middle school and instantly became friends, which is impressive when you consider that cooties was a “real thing“ at that age. As the years went on and recess turned into high school study halls their friendship continued until one day Fraser asked Christen to be his girlfriend. At that time he was in the “friend zone” therefore Christen said no not realizing how much she actually liked him.
So Fraser moved on and began dating someone else and Christen did too. This led to them becoming archenemies, hindsight they realized it was jealousy as they both truly wanted to be dating each other. High school graduation came and they both went different directions attending separate colleges. But… Fraser was not giving up that easily. They eventually started talking again and over dinner + a movie he asked her to be his girlfriend once more. Only this time she said YES!
