Chen Yan is a former special forces operative living in obscurity as a temporary laborer at a barbecue restaurant. After being fired and facing financial ruin, he intervenes in a rainy night to rescue Su Qingyuan, the cold and formidable CEO of the Su Group, from three thugs. Su Qingyuan, who is known as the Iceberg CEO for her ruthless business acumen, is intrigued by Chen Yan’s effortless combat skills and his refusal to accept a monetary reward for his help. She tracks him down through Wi-Fi logs and offers him a job as her live-in personal assistant with a high salary, seeking someone reliable to manage her chaotic personal life.
Chen Yan accepts the position and moves into Su Qingyuan’s luxurious villa, where he discovers that the powerful CEO is helpless in domestic matters. She cannot cook, is afraid of the dark, and lives in a state of disarray. As Chen Yan cleans the house and manages her daily routine, a subtle dynamic develops between them. He handles her household needs with competence and quiet care, while she begins to rely on his presence. Their relationship deepens during a business trip where Chen Yan provides strategic advice that helps Su Qingyuan expose financial fraud in a corporate partnership, revealing his deep understanding of business warfare that contradicts his humble assistant persona.
The narrative introduces Su Qingyuan’s younger sister, Su Qingyue, a criminal investigation student who becomes an amateur detective regarding her sister’s relationship with Chen Yan. She observes their interactions and concludes that they are secretly in love, though both deny any romantic involvement. Meanwhile, Zhao Yuchen, the wealthy heir of a rival company and a persistent suitor of Su Qingyuan, confronts Chen Yan at the villa. Zhao mocks Chen Yan’s low social status and attempts to intimidate him, but Chen Yan calmly defends Su Qingyuan’s dignity by pointing out Zhao’s fundamental lack of understanding of her preferences. Su Qingyuan publicly declares Chen Yan as her man to protect him from Zhao’s insults, marking a significant shift in their relationship.
Later, the Su Group faces a critical supply chain crisis when their largest supplier, Huasheng, cuts off deliveries to pressure the company into unfavorable contract terms. Chen Yan devises a counter-strategy, advising Su Qingyuan to feign interest in renewing the contract while secretly preparing to switch suppliers. This psychological maneuver causes Huasheng to panic, leading them to restore supplies and beg for reconciliation. Through these events, Chen Yan’s true identity and past remain hidden, but his competence and loyalty earn Su Qingyuan’s growing trust and affection. The story concludes with the two navigating their professional and personal lives together, with Su Qingyuan increasingly aware of her feelings for Chen Yan despite his reserved nature.
