Shen Yanzhou, who was burdened with huge debts, chose to marry into the Su family to save his father, and became the contracted husband of Su Wanyi, the "iceberg female CEO". In a wealthy family, he was made difficult by his mother-in-law and suppressed in the workplace, so he could only work part-time late at night to make a living. Su Wanyi initially only saw him as a shield, but in the daily fireworks, she got a glimpse of his forbearing talent and responsibility. She quietly protected and trusted him, becoming the only light in his gloomy life. When family strife and villain schemes ensue, Shen Yanzhou's dormant talents gradually emerge. He went against the current, and with Su Wanyi's full support, he made waves in the workplace and business world, and gradually shattered the label of "waste son-in-law". From contractual allies to soul mates, the two worked together to write a sweet and evenly matched counterattack amidst the siege of mortgages, workplaces, and family struggles, and built a warm future together in the world of fireworks.
