Some things in the world repeat like the rising and setting of the sun, never changing.
For example, Shen Qingming's anger.
In the past two months of getting along with her, Wang Jiu could hardly find a day when she wouldn't get angry. The reasons for her anger, however, were always strange and varied. For instance, bringing her hot water when she's injured could make her angry. Helping her stick to her persistence when she's determined to do so, keeping her away from gourmet food and eating wild vegetable soup instead, could make her angry. Inviting her to taste Jiuzhou Era's specialty cuisine from Qing Province could make her angry too... It's completely impossible to summarize any pattern, so after much consideration, Wang Jiu could only regard Shen Qingming's anger as a natural phenomenon like sunrise and sunset, unmoved by any external factors.
No matter what you do, the sun always rises as usual.
