Lin Haoran, an ordinary young working man, was pushed to the position of the Su family's son-in-law by fate. Faced with the cold eyes of the Su family, the difficulties of relatives and friends, and the disdain of his father-in-law and mother-in-law, he cleverly resolved the embarrassment with his sense of humor, and was full of laughter all the way. Amid family conflicts, wealthy families and adversities in life, he not only won Su Wanqing's heart with his extraordinary emotional intelligence and wit, but also won the recognition of his parents-in-law. In terms of career, Lin Haoran made several comebacks, turning crises into opportunities, and achieved life transformation in the collision of career, love, family and self-growth. The three-volume story progresses step by step, being relatively independent but also echoing back and forth. It interprets the ups and downs of the son-in-law's counterattack in a relaxed and humorous style, and finally ends successfully.
