Flashback.
"Have you done my homework?" Rui asked, plopping on Kaiden's worn mattress. It was something his aunt had picked up from the side of the road. However, it was much better than sleeping on the cold, hard floor.
Kaiden sighed and gave him his workbook. "Yes, here," he muttered.
Rui smirked, grabbing the book from him. "Really, it's amazing that you're good at this. But then again, the world is pretty fair. You can't walk but you're pretty smart."
Kaiden shook his head and continued reading the book that he bought with his own allowance.
"What is that?" Rui asked, taking the book from him.
Kaiden pursed his lips and held out his hand. "I'm reading it," he said.
Rui ignored Kai and read the contents of the book. "Physics? Who reads things like this at our age?"
Kaiden sighed and grabbed it away from him. "It's interesting," he muttered.
