Everyone knew that Miss Du was secretly attracted to Hong Xulin romantically.
However, the Du family wasn't any less powerful than the Hong family, and Hong Xulin didn't want to be tangled up with Miss Du.
If they really did become attached to each other, once the two families were connected by their marriage, he wouldn't be able to fool around outside anymore.
Hong Xulin was treating a woman he was meeting for the first time in such an amiable manner. Some might even call it obsequious. Miss Du immediately held a grudge against Zhao Chuchu.
The reason why Miss Du kept trying to make trouble for Yuan Hui was also that Yuan Hui had always gone against Hong Xulin. Miss Du felt that Yuan Hui was purposely trying to attract Hong Xulin's attention. This was why whenever Miss Du appeared, Yuan Hui would lose face.
