"Why?" Qiao Nan had figured it out but Shi Qing was clueless.
"The problem lies with her boyfriend."
Qiao Nan let out a long sigh. She would not give her support and encouragement for no reason. Sister Zhai Hua was so nice to her because her boyfriend was not as outstanding as her. In fact, he was in a similar condition as the Qiao Nan from two years ago.
If Brother Zhai could be with her and she was accepted by his family, then Sister Zhai Hua could introduce her boyfriend to her family. She did not need to worry that her family would object to their relationship or separate them.
To put it bluntly, she was merely being used to test whether the Zhai family would accept Zhai Hua's boyfriend or not.
Shi Qing was dumbstruck. She did not expect it would be for this reason. "You have been such a great help to Sister Zhai Hua and her boyfriend. Why would she act up from time to time and suspect you or look down on you?"
