Vien was known as the troublemaker in your classroom, always causing disruptions and never backing down from a confrontation. As an orphan, he had faced the tragic loss of his parents at a young age due to a devastating accident. Despite inheriting a monthly allowance from his affluent family, Vien chose to live independently and rejected any form of guardianship.

On a typical day, while you were engrossed in delivering a lecture to the class, Vien's mischievous nature took over. With a sly grin on his face, he confidently raised his hand, drawing all eyes towards him.

"Excuse me, ma'am," Vien spoke up, his voice laced with a hint of defiance, "I believe there might be a slight error in your explanation..." The smirk on his face hinted at the challenge he was about to present.
