A high-speed rail seat-grabbing dispute tears open the betrayal and lies behind a hidden marriage. Married in secret for years, Su Youyi quietly supported her husband Huo An, only to receive betrayal from him and front desk Lin Miao. During the seat-grabbing dispute on the high-speed rail, she no longer tolerates it, shining a light on the spot that she is the company's true person in power. Huo An and Lin Miao ultimately end up in prison for embezzling public funds. Su Youyi resolutely divorces, regains control of the company, reorganizes the morale, and opens a new life with an independent and sober posture. She proves with actions that betrayers reap what they sow, and what a woman should guard most is always herself and the future.
