"Huh? What piano teacher?" Yang Gang was full of question marks.
Ye Qing looked at Yang Gang in surprise, "Aren't you her brother? You don't know?"
"Oh, I had a car accident not long ago and forgot a lot of things," Yang Gang paused before continuing, "What was that about a piano teacher you just mentioned?"
"Well..." Ye Qing hesitated slightly before saying lightly, "Actually, I met your sister a long time ago. About three years ago, I came to Hangcheng on business. As I passed a training institute, I heard an extremely beautiful piano duet coming from one of the piano rooms. I am a big fan of piano music, so I sneaked to the window and looked inside. There were only two people in the piano room - one was Yang Fei who was about sixteen or seventeen at that time. The other was a young man in his twenties, who I later learned was named Sima Bing, a teacher at the training institute."
