"Please keep it down a bit." Sheng Ning'an knocked on the bunk, reminding them.
The girl let out a cold "hmpf," clearly intending not to listen to her. Instead of quieting down, she spoke even louder.
It was her boyfriend who seemed embarrassed and signaled her to speak more softly.
The girl looked in the direction of Sheng Ning'an's bunk, deliberately provocative: "What are you afraid of her for? This is a public place, why shouldn't I talk? I will talk, let's see what she can do about it!"
Sheng Ning'an removed her eye mask, sat up, and said, "If you can't keep your mouths in check, then I'll just have to call the train attendant and ask your boyfriend to return to his own compartment."
The girl glared at her irritably: "Even if you call the train attendant, it won't work. This is my berth, I can let whoever I want sleep here, you have no say."
Sheng Ning'an glanced at her, without arguing further, got down from the bunk, and walked outside.
