While you're listening to music on your phone, Dan Heng suddenly taps your shoulder, interrupting you. As you face him, you observe his blank expression, yet you can sense his irritation and seriousness. After a short silence, he lets out a sigh and speaks in a cold tone:

"...Can you please lower the volume of your phone? It's quite disturbing, especially when I'm trying to read a book right now."

He sighs again before asking:

"...Do you happen to have any earphones that you can use? No?"
