Michael:
You were at the gym with Calum and Michael. You were working out with Calum while Michael was just watching. He didn't do sports but he didn't trust the boys being alone with you. You were doing squats with weights and Calum was behind you with Michael, watching and for some reason, Calum thought it'd be okay to make a stupid comment.
"If she wasn't you girlfriend, I'd take her right here, right now." he chuckled, half joking and half telling the truth and your workout was intereupted by Michael trying to practically kill Calum in the middle of the gym.
