The Lu family is a well-known wealthy family in the capital, with a large family business and strict rules. It just so happened that in this generation, a "freak" appeared - Lu Yanchi, the eldest son of Lu, had outstanding abilities, but was cold-blooded and unkind. He also suffered from strange diseases and was bedridden all year round. For the sake of happiness, and to stop Yunyu from talking to all parties, the Lu family decided to marry him a wife. Naturally, the candidates cannot be those young ladies with backgrounds and ambitions. What the Lu family wants is someone who is obedient, doesn't cause trouble, and is preferably a "transparent person". So, they chose Su Wan. Su Wan, a branch of the Su family, had been living under someone else's roof since she was a child, and her temperament was as quiet as air. The elders say that she "knows the general picture", but in fact she is easy to handle. She has no prominent family background, no stunning appearance, and no means to gain a foothold in a wealthy family. From the Lu family's perspective, Su Wan was a perfect "failed plan" - her marriage would not threaten anyone's interests, and she would never achieve anything famous. When Lu Yanchi dies of illness, she will naturally be sent away and everything will return to where it started. However, no one expected that Su Wan, who was despised by everyone and only treated as a decoration, would quietly change everything the moment he stepped into the Lu family's door. Lu Yanchi, the man who was declared by doctors to not live to live past thirty, miraculously improved under her meticulous care. His cold eyes gradually gained warmth. There is internal fighting in the family and undercurrents are surging. Those tribesmen who thought Su Wan was a soft persimmon and wanted to use her hand to attack Lu Yanchi found that this "transparent person" had amazing insight and wisdom. She doesn't fight or grab, but she can always move a thousand pounds.
