Ms. Niu firmly believed that Ms. Zhang was responsible for all the troubles their family had endured, and she had no intention of giving her an easy time considering their past conflicts.
Ms. Zhang was constantly tormented by Ms. Niu, and this constant torment had further deteriorated her original personality, making her even more sinister.
She harbored a deep hatred for them, especially Ms. Niu. However, she didn't dare retaliate against Ms. Niu, as she was her mother-in-law and a senior figure in the family. She knew that if she did anything to Ms. Niu, her own suffering would only worsen, especially since she was already in a difficult situation without provoking Ms. Niu.
A mother-in-law needed no excuse to berate her daughter-in-law. In this house, excuses were unnecessary.
