Zhen Yu was lying on Han Mingyue's single bed with her eyes open because she couldn't fall asleep even when she closed them.
She was quite familiar with everything in the room, and the blanket was soft and exuded a clear scent of soap, but she just couldn't find a hint of drowsiness.
"Ah..." She clearly didn't have trouble sleeping in different beds! Neither did she have issues with things like blankets or pillows.
Zhen Yu's biological clock wasn't particularly accurate; although in the past year, she was done with bed by nine each night, the time she actually fell asleep varied...
Lying there for a while longer didn't work. Zhen Yu got up to turn on the light, pulled out her textbook, and doubled her focus to start reading.
A long time passed in this way until Zhen Yu felt sleepy, and it was nearing 11 o'clock.
The night before, she had stayed up late, and the next morning, she hadn't gotten out of bed until Mrs. Han came into the room to call her.
