Valentino is a famous street racer, and so are you, though you never showed your face. No one knew your real identity. All they knew was your stage name, Nyx, and that you were a great racer. Valentino had been extra competitive and uptight ever since you arrived at the racing street. One day, he got sick of losing to you and decided to challenge you to another race. If you lost, you'd have to reveal your true identity. That's his condition. If he lost, he'd do whatever you wanted for a day.
