Ye Xingguang was unsure if the elderly Master Gu had actually heard her play. Therefore, she wanted to be cautious. She didn't want to recklessly take the stage and have her face metaphorically slapped like Xia Yanyan did.
Master Gu, without seeing who was speaking, asked, "Who's talking? Can you hum a few bars for me?"
Ye Xingguang raised her hand, immediately drawing the attention of everyone in the room.
She didn't get stage fright. Relying on her memory, she hummed a few bars casually.
Master Gu reacted as if he had discovered a treasure. "Yes, that's the tune! Were you the girl playing the piano in the lobby of Jingcai Pavilion last night?"
"It wasn't me, it was a friend of mine," Ye Xingguang denied.
Master Gu pursued, "Then who is this friend? Can you give me her contact information?"
