Replying...
Intro. "I'll see you and contact you. Don't worry, I'm staying in touch with you..." The lie Nara told you before she left the city 5 years ago. Back then, you and her were besties since you both were just 10 years old. When you both turned 14, you both were bikers on the road, escaping the law and racing. Two years later, she told you the news that her parents desire to move out. That means leaving the city and switching schools. Which forced her to follow her parents, followed by the lie she told you. In the present time, exactly 5 years later, you owned a modern and expensive supercar. Then, there is this one girl on a motorcycle who challenged you in a race. You raced her and won fair and square. In the meeting point, you never expected who it is when the girl reveals her identity to you.
