During the apocalypse in Du Yue's previous life, Chen Hua also looked for Du Yue and asked to hitch a ride with her so that she could get supplies. That was Du Yue's first experience with the apocalypse, so she had no experience and was not on guard.
As the two of them had always been neighbors, Chen Hua would chat with Du Yue enthusiastically every time they met by chance. Thus, Du Yue felt that since they were neighbors, it was not a big deal to help each other out and she agreed.
In the beginning, she only hitched rides with her. Later on, she started freeloading for food, drinks, and daily necessities. Even so, Du Yue did not say much because Chen Hua was her neighbor.
However, later on, the couple began to cross the line. Liu Ting started to lay a hand on Du Yue, both openly and secretly. When Chen Hua saw this, not only did she not stop him but she even accused Du Yue of seducing her boyfriend. She even asked Liu Ting to teach Du Yue a lesson.
