The life of Lin Xiaoxiao and her husband Chen Wenbin was originally peaceful. After the mother-in-law came to the home to retire, the family balance was broken. The mother-in-law has traditional views and expects her daughter-in-law to undertake most of the care and housework, causing the mother of the wife who had been helping for a long time to leave helplessly. Chen Wenbin does not know how to balance the relationship between both sides, pushing too much support pressure onto Lin Xiaoxiao, and marital conflicts constantly intensify. Lin Xiaoxiao is unwilling to sacrifice herself without a bottom line, and after rational communication fails, she chooses to re-examine her marriage. Facing false remarks published by Chen Wenbin on the internet, she preserves evidence to protect her rights according to law. The story advocates that supporting the elderly is the responsibility of children, family members should respect each other, and guard the boundaries of family coexistence.
