Zhong Yansheng lived for eighteen years. After accidentally falling into the water, he dreamed and found that he was living in a book. In the book, he was a fake young master who was mistakenly adopted by the Marquis. After the real young master came back, he {real} was not taken seriously by the family and was driven to a separate courtyard in the suburbs of Beijing. His parents only doted on him {fake}, and they turned the real young master into a black hearted man, and finally his family was ruined. After waking up, Zhong Yansheng learned the news that Master Zhen returned to the house three days ago, but the whole family only revolved around him {fake} who was sick.

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

Cen Shuang used to be the daughter of a wealthy family. After she fell from grace, she was forced to bend her back just to make sure she had enough food. She was sold by her uncle for 10 million to the wealthy Zhuang family as the bride that would counter the bad luck in the Zhuang family.

She married Young Master Zhuang, who went into a comatose after a car accident. Everyone viewed the marriage between the fallen daughter of a once rich family and the comatose young master as ridiculous.

The socialites who were once under Cen Shuang’s feet were all waiting to see Cen Shuang make a fool of herself. Unexpectedly, on the night of their wedding, Zhuang Hong, who was in a vegetative state, suddenly woke up.

Cen Shuang instantly transformed into the Zhuang family’s benefactor, and the Zhuang family were extremely protective of her as they doted on her. Grandpa Zhuang asked, “Lil Shuang’er, do you want a black card?”

Mr. Zhuang asked, “Lil Shuang’er, are you bored staying at home all day? Should I give you a company to toy around with?” Mrs. Zhuang said, “This is the newest season’s haute couture. Throw those in the last season away since you’ve already worn them.”

Zhuang Hong, “Nothing about my wife concerns you!” From necessities to food and accommodation, the man did everything himself and spoilt Cen Shuang to the extremes.

Outsiders were jealous of Cen Shuang’s good fortune, but little did they know that this joyous occasion had been long premeditated. Zhuang Hong, “A single look lasted for ten thousand years. After many twists and turns, I finally married the girl I like.”

Cen Shuang, “I thought that there will only be darkness in my life, but there’s a silver lining waiting for me.”
