"Mr. Lu, Madam Her Waistcoat Has Fallen Off Again" is a modern romance novel that combines the grudges of wealthy families, suspenseful plots and sweet love. In order to save the family from crisis, art teacher Lin Youran was forced to marry wealthy heir Lu Chenfeng. It seems to be a cold business marriage, but in fact there is an undercurrent - she was assassinated on her wedding night. She used her amazing skills to fight back against the assassin, revealing her hidden identity as a field doctor.
Lu Chenfeng gradually discovered that this seemingly weak "painter" wife was actually a former international rescue doctor code-named "Iris", who had become anonymous because of her involvement in the biochemical weapons conspiracy of arms dealer Mendoza. The two went from being suspicious of each other to working together to deal with family infighting, port equity confusion and transnational crises.
When the truth about Mr. Lu's illegitimate son comes to light, Mendoza's revenge plan gradually becomes clear - not only does he want to regain the family business, but he also wants to destroy everything about Lu Chenfeng. And the psychiatrist Li Mingxuan, who has always been lurking as an "old friend", is actually Mendoza's most deeply buried chess piece.
Lin Youran and Lu Chenfeng worked together step by step in the crisis, growing from a contracted couple to each other's most trusting comrades and lovers. They must work together to uncover the sins of their fathers, crush biological and chemical attacks, protect innocent lives, and make life and death decisions in the final showdown.
The plot of the novel is compact and constantly reversing, with both the smoke-filled battle scenes and the delicate and moving emotional development, creating an image of a wise and brave heroine. It is an addictive work of confrontation between powerful forces.
