Yu Dong originally wanted to go to Song Yixu's restaurant and look for help but then halfway through she changed her mind. These days she has been relying on Song Yixu and Sister Xi more and more, though the two of them were nice to her but that was purely because Yu Dong was capable and brought many advantages to them.
True, there might be good feelings involved somewhere but Yu Dong understood that their relationship was mostly contractual. She had to be more self-reliant than just rushing to sister Xi for every little thing. Or else she might end up owing a lot to Sister Xi, and that might affect their business relationship.
