Judging from the warmup exercises he was performing, the young man was preparing for a chorus.
When he noticed Fang Zhao approaching, the young man began to interrupt his practice. When he stopped and realized Fang Zhao was seeking him out, he panicked.
"So-so-so-sorry. Am I bo-bo-bo-bothering you?" the young man stuttered.
"No, not at all. Carry on. I’m just listening." Fang Zhao sat in a chair in the corner. The corner was empty. The other singers were avoiding the area and the chairs were all unoccupied.
The young man scratched his head hesitantly. He glanced at Fang Zhao and the onlookers. He opened his mouth but couldn’t continue. It just felt like he was surrounded by a crowd that was focused on him. What if he was so afraid and nervous that his voice scared people away? Would they kick him out?
