Chen Jingming and Liu Huilan have been married for twenty years and run a community convenience store that barely makes ends meet. Their daughter Chen Yutong has just entered high school, and her mother Zhang Guifen has come to live with her from her hometown. There is no small warmth in the life of a family of four, but only constant conflicts, misunderstandings and hidden grievances in their hearts, full of cruelty and regret. Zhang Guifen has been strong and paranoid all her life. Because she lost her husband at an early age, she pinned all her hopes on her son Chen Jingming. After coming to the city, she still couldn't stand her daughter-in-law Liu Huilan, feeling that she was not worthy of her son. She often beat, scolded, and complained. She didn't know how to run a household, couldn't make money, and even slandered her in front of her neighbors. She also forcibly interfered with Chen Yutong's study and life choices, forcing her to drop out of school and work to support the family. Liu Huilan had a weak and forbearing temperament, and had been silently working for her daughter and this family. Despite being made difficult by her mother-in-law, she never dared to resist even if she was wronged or treated harshly. Over time, the accumulated grievances became a heartache, but she didn't even have anyone to talk to - Chen Jingming was caught between his mother and his wife, always choosing to favor his mother. , Felt that Liu Huilan was not sensible enough and would not accommodate the elderly. Even if she saw her mother mistreating her wife with her own eyes, she would only advise Liu Huilan to endure it and never really support her. She would even occasionally quarrel and have a cold war with Liu Huilan because of her mother's instigation. Chen Yutong grew up in such a repressive family environment. He not only had to endure the harsh criticism and control of his grandmother, but also had to watch his mother being bullied and his parents' endless quarrels. He gradually became sensitive, inferior, and taciturn. His adolescent rebellion was suppressed and turned into internal friction. His grades plummeted, and he even became tired of studying.
