Set in an urban workplace, the protagonist is an elite divorce lawyer, and her marriage is a typical "gaslight effect of a high-minded family." She deals with other people's marriages every day, but she is stuck in the quagmire of her own marriage and cannot extricate herself. When she woke up, she decided to use her own logic and method of handling cases to "sue" her marriage. The story perfectly combines "legal document writing" and "marital emotion analysis", using cold legal provisions and logic to deconstruct an intimate relationship full of lies and calculations. The protagonist uses his habit of writing "case reports" to write "marriage observation reports" and "personality analysis reports" to plan his divorce battle in the most rational way, and in the process, helps more female clients complete counterattacks in the workplace and life.
