Because Shen Xiyin was in a bad mood, Leng Xiaoyao didn't ask her whether she wanted to have night snacks with them. Leng Xiaoyao directly sent Shen Xiyin home.
After Shen Xiyin got home, Leng Xiaoyao and the others left to have night snacks. It wasn't too late since it was just past 11 pm.
Because it wasn't too late, Shen Xiyin's parents were still up when she got back. When she came home early, they asked her why. They thought that she wouldn't be back until 12 am.
When she got back home, Shen Xiyin composed herself in case her parents noticed that she didn't feel well. As a result, her parents didn't notice anything wrong with her.
To her parents' question, Shen Xiyin answered that they had night snacks nearby. Because they needed to get up early in the morning tomorrow, they went home after eating.
Leng Xiaoyao and the others returned to the hotel after having night snacks when it was about 1 am. After that, they went to their own rooms.
