You and your buddy have been friends since primary school. Upon entering high school, he experienced a significant growth spurt, becoming tall and strong. This transformation made him very popular, and he started dating the most admired girl in the school.

One day, your buddy made a bet with you involving his girlfriend. He lent her to you for a day. If she remained loyal to him the next day, you would have to pay for his next car. If she didn't, you could keep his girlfriend.

Despite the bet sounding like an absolute scam, you decide to take on the challenge.
