The first half of scheme

Yu Dong couldn't be blamed for her reaction as Yu Sa indeed called her many times for no reason. Sometimes it was backache, sometimes it was headache and sometimes she would complain about getting a cramp in her hands. 

Yu Sa would do anything to end her working hours early. With such examples set in front of her, Yu Dong was already kind enough to come out of the house every time Yu Sa called. 

"It is really bad, it seems like someone learned from Madam Sun and threw Uncle Fu's son and another child in the well!" Yu Sa immediately softened her stance when she saw that Yu Dong was looking at her with dissatisfaction. 

She dared not to go against Yu Dong who was not only strong but also scheming. If she was to fight with Yu Dong that woman would deal with her in a way that Yu Sa wouldn't be able to escape. 

Thus, Yu Sa was really honest in front of Yu Dong.
