Su Nanzhi's phone was on, and she had received many calls.
Several of them were from unfamiliar numbers.
Some had names attached to them.
When Su Nanzhi and An Yunhuai returned, Auntie Dong was there. No one had eaten the lunch she made today; there were no signs that either sibling had been home, which worried her, so she made several calls.
No one answered Su Nanzhi's phone, nor An Yunhuai's.
The food she made went untouched.
Auntie Dong usually waited for them to finish their meal before washing the dishes and leaving, but today, since the siblings didn't come home and didn't answer their phones, nor gave any prior notice, she didn't have anything else to do that afternoon, so she simply waited there.
Now that she saw both of them had returned, she felt relieved, "Xiaozhi, Xiaohuai, you're back."
Su Nanzhi roughly understood why Auntie Dong was here; when she was looking for someone to take care of An Yunhuai, one of the requirements was to be responsible.
