Li Shasha worked in administration at her husband's company for three years with a monthly salary of three thousand, until she saw the salary slip of the new intern: fifty thousand. Rummaging through her old phone, she discovered that three years ago her mother-in-law and husband had already planned for her to resign, take a low salary, and prepare for pregnancy at home. Without making a fuss, she went to a rival company after her contract expired. Her ex-husband sued her for infringing on trade secrets; in court, she produced key evidence and won the lawsuit. A year later, she signed a partner agreement, and the receptionist said someone was applying for customer service: his name was Lu Zheng.
