The heroine is an "invisible wife" in marriage and a "screw" in the workplace. Her marriage to her husband is an invisible transaction that no one knows about. When her husband prepares for a public divorce and gets rid of her as an obstacle to his future, the heroine wakes up from the seemingly passive situation and uses the hidden power (connections, information, intelligence) she has accumulated in her family and basic positions for many years to backhand layout in the workplace and the love field at the same time, making her ex-husband realize that what he has abandoned is not a nanny, but an entire business intelligence network.
