The human heart is always biased.
Jing Shasha is her own granddaughter, sharing their blood. Compared to Loo Zhongtang's children from his previous marriage, she and her husband naturally favor Jing Shasha more.
Every time she and her husband embrace Jing Shasha affectionately, Loo Zhongtang's daughter from his previous wife, Loo Yaxin, would become very jealous.
When Loo Zhongtang returns home, she clings to him crying as if the entire family is mistreating her.
Clearly, the family treats her well too, but she seems to be naturally jealous, wanting to compete with Shasha in everything, wanting to surpass Shasha in everything.
The older she gets, the more evident this trend becomes, and her relationship with Shasha worsens.
Because of her interference, the relationship between Loo Zhongtang and his eldest daughter deteriorates every year.
Yet, even so, the elderly couple tries to mediate, thinking that Loo Yaxin would eventually be married off.
