Su Wan is the most shady illegitimate daughter of the Shen family. She was forced to marry her sister's heir to the Gu family, who was rumored to be a wife-suppressant. It was only on the wedding day that she learned her husband's name - Gu Linyuan, the most cold-blooded man in the capital's business world. On their wedding night, he threw her a contract: each should live his own life and not interfere with each other, and he would take the money and leave in two years. She signed happily, thinking that the marriage was just a deal. But he brought warm water to her late at night when she had a stomachache, silently changed work stations when she was ostracized by her colleagues, and took off his coat and put it on her shoulders in public at a family banquet. His concern was never expressed out loud, but was hidden in every detail. She thought he had a cold nature until she discovered that the study on the third floor was filled with photos of her from the age of seventeen to now. It turned out that he was the person she accidentally saved on that rainy night three years ago. And he had been waiting for this marriage for three full years.
