The young man was speaking fluent Korean, clearly not from China.
In the car, Zhao Sishang, also confused, didn't understand Korean at all!
Before Musheng could speak, Zhao Sishang tried to use English, "I'm sorry, did you get on the wrong car?"
But the boy seemed even more bewildered...
However, he clearly realized he had gotten into the wrong car, glancing forward subconsciously; their car had already driven quite a distance, and nobody seemed to remember the forlorn him...
So the boy, with a pitiful look, stammered in broken Chinese, "Sor... sorry... sister, I... wrong... wrong car...!"
Listening to him speak Chinese was torturous because he was obviously not proficient, sometimes even getting the tones wrong, almost like listening to an indecipherable code, but the situation was awkward.
Assessing him, Musheng replied indifferently in Korean, "Are you a member of that group that just left? Your group's car has driven away."
