Teacher, Is This Your First Time?

“Teacher, I don’t understand this problem.” The one who raised their hand to call me over was Woo Tae-seon. Second row from the back. The closer I got to him, the more I crossed the classroom, a cold chill ran down my spine. Woo Tae-seon slowly moved the pen he was holding. Each time his neat fingers shifted slightly to the right, letters that had been hidden by his hand became visible one by one.
