Yun Qian is a strategist armed with a System that lets her transmigrate into a book. Her main mission is to win over the second male lead, Hao Yuan, ruler of the underworld who controls life, death, and reincarnation.
It takes Yun Qian ten years, but she successfully wins over the devoted second male lead, Hao Yuan, and makes him fall deeply in love with her.
Yun Qian falls deeply in love with Hao Yuan, too. When faced with the choice between returning to the modern world and staying in the world of the novel, she chooses to stay.
After their marriage, they remain as loving as ever, never misunderstanding or arguing with each other.
Even Yun Qian believes she has married a good man.
That is, until three hundred years later, when Hao Yuan secretly brings the heroine, Bai Xiyan, back to the underworld, and Yun Qian accidentally overhears their conversation.
“Xiyan, do you know? You’ve always been the woman I love most.”
“I only married Yun Qian because she looks so much like you.”
Yun Qian is struck as if by lightning, unable to believe what she has heard.
It turns out Hao Yuan doesn’t love her at all. He has only ever treated her as the heroine’s substitute.
Because they look so much alike, he simply went along with the mistake, fell in love with her, and married her.
After learning the whole truth, Yun Qian sheds no tears of sorrow. Instead, she calls forth the System that has been dormant for years.
“System, I want to go home.”
