Qin Qing is a male college student and an heir to a family of ancient martial artists, trained in lightness skills. His attack power is weak, but his evasion is maxed out.
One day, he is bound to a transmigration-into-a-book System and transmigrates into a novel about a domineering male lead, becoming a disposable tool character. He is a shuang'er, a man who can bear children.
Although the original host is the same mother's child as Qin Qing, the fourth prince and the novel's domineering male lead, his mother abandoned him at birth because of his sex and a prophecy. From then on, he lives worse than a dog or a pig.
As the male lead's foil, the domineering hero gathers a harem and loyal followers amid the chaos of war, claims the world, and lives a carefree life. The original host, meanwhile, is only ever his shadow, bodyguard, substitute, and scapegoat. He is gloomy and insecure, so insignificant that no one notices him. Nobody knows of his existence from birth to death.
Just after Qin Qing transmigrates, the male lead botches an assignment. To teach him a lesson, the emperor issues an imperial decree granting him a marriage to Lu Huan, the frail eldest princess of Xiliang, as his principal wife.
The male lead is too busy flirting with all the beautiful women around him, so he orders the original host to disguise his sex, dress as a man, and take his place at the wedding.
His new bride, Lu Huan, is frail and destined to die young. She is a famous beautiful-but-tragic character in the book, and Qin Qing's favorite character, his idealized beloved. Her twin brother, Lu Huan, is the novel's greatest villain, the strongest fighter in the story, and an imposing presence. Unfortunately, he has terrible luck and is always coughing up blood. The novel says he and his sister are very close, and her death is what finally drives him to become a true villain.
On their wedding night, they sit facing each other. Looking at the beautiful bride, dressed in red wedding robes, Qin Qing remembers his original body's sex, and his hot blood slowly cools: My sex makes this impossible. We can only be friends. I hate this!
At the same time, he secretly vows to protect the beloved he cherishes and stop the great villain Lu Huan from turning evil!
The princess is gentle and considerate, and notices Qin Qing's reluctance. She takes the initiative and says, "I have always been frail, so I fear I may be unable to bear children. I hope Your Highness will be understanding. If you take concubines, I won't object. Even if it's because we have no heirs, or if you fall in love with someone else someday and want me to give up my position as your principal wife, a letter of divorce will suffice. I won't make things difficult for you."
The princess pleads again and again, yielding to him so completely that Qin Qing can only agree.
From then on, Qin Qing takes the utmost care of Lu Huan. Gradually, the eldest princess starts looking at him in a way that feels more and more strange.
Until one day, after the princess is drugged, she breathes heavily and pins him to the bed, kissing him fiercely. Qin Qing is stunned:
"You're a man?"
Then she keeps kissing him until he's dazed. Qin Qing thinks woozily: He's a man, and I'm a shuang'er. I guess there's no problem.
Suddenly, he remembers the great villain Lu Huan from the original novel. He shoves away the eldest princess, still dressed as a woman, his pupils trembling as his voice nearly fails him:
"Y-you're Lu Huan?!" The ruthless villain from the original novel, the one who always repays every slight tenfold?
A few months later
"Congratulations, Your Highness! You're expecting!"
With his belly swelling, Qin Qing casts a sidelong glance at the person who is overjoyed to hear that he's pregnant, and gives a silent, cold laugh:
So much for divorce?
So much for being unable to bear heirs?
So much for taking concubines whenever you like and never getting jealous?
So much for giving up the position of principal wife without any fuss?
A man's words really are just lies!
