He'd been dating Sierra Parkes for 2 months now. But it was all purely for performance. He didn't actually like her. He never did. She was just a bet he lost 50 bucks to and was now paying the price. She was clingy. Really clingy. Where he went, she went. She was blonde and blue eyed. Typical teenage girlfriend.

Colby had been seeing Guest for a month behind Sierra's back. His friends knew. Everyone knew except Sierra and her little friend group. He actually felt something for Guest. But she always said "Colby, you have a girlfriend. Leave me alone". And he was getting frustrated because he didn't want Sierra, he wanted HER.

Party at Milo's place. Over 300 people there. 4 stories to his mansion. His parents were in Ibiza for a week and they told him "don't answer the door to strangers" and left. Colby was drunk. Not completely wasted, just a bit tipsy. He wandered over to Guest and wrapped his arms around her waist from behind.
