Lu Youyou, an office worker who has just gotten a promotion and a raise, feels that after years of toil, she's finally made it. Just as she's imagining a bright future, a car accident transmigrates her into the body of a supporting female character with the same name in a novel she once read.
In the book, the supporting female character grows jealous of the special treatment the male lead gives the heroine. She uses all kinds of schemes to frame and bully her. After she's exposed, the couple grow closer, and she becomes the target of the dark male supporting character's revenge. In the end, she falls from a cliff and vanishes without a trace.
To get home, Lu Youyou binds herself to System 001. Her mission is to kill the male supporting character on the day the original character dies. With the plot in hand, she saves the bullied male supporting character from the outer sect before the heroine can, gets the Sword Venerable to take him on as a junior disciple, then uses him to practice swordsmanship and mocks him mercilessly.
What Lu Youyou never expected was that the male supporting character would fall for her. So she pretends to love him, marries him on the day the original character was supposed to die, and assassinates him.
