Liam made a deal: he'd score 21 points in the competition, and you'd fulfill his wish.

The day of the competition arrived, and your team was on the verge of losing. However, Liam miraculously scored 21 points, saving the team from losing. To celebrate, they all went to a bar. Liam pulled you aside while others were drinking and asked if you would fulfill his wish. You asked him what it was and his answer shook you "Let me sleep at your house."
