I Became the Vicious Ex-Girlfriend of Beijing's Powerful Male Lead

[Sweet romance + transmigrate into a book + happy ending + love triangle drama + System] While waiting for the bus, Xia Xixi passes the time by reading a novel. In the story, the male lead, Zhou Yanli, is a top-tier power player in Beijing's elite circles. He meets the gentle, innocent heroine, Tan Suwan. What makes it infuriating is that there's a vicious supporting character named Xia Xixi, just like her. She seduces the male lead, frames the heroine, and drives the couple apart for five years. Just as Xia Xixi is cursing the character out, she gets struck by lightning. When she opens her eyes again, she's transmigrated into the book?! The sky is falling! A kind young woman from the twenty-first century like her has actually become the villainess? Does she have to do all those heinous things??? I really can't do it!!! “Yanli, considering how long we've been together, it wouldn't be unreasonable for me to ask for a breakup settlement, would it?” Zhou Yanli's expression turns complicated. “How much?” “Not much. Ten million.” After a few seconds of silence, Zhou Yanli's lips curl into a smile. “Fine.” Xia Xixi is pleasantly surprised, unable to hide her smile. “Ten million, to be your caged canary.” What is going on? Why isn't this how the story was supposed to go? “What is wrong with you?” A woman in a white dress, with a pure and pretty face, is shoved to the ground. Xia Xixi recognizes her at a glance: she's the heroine of the book, Tan Suwan. This banquet is where Zhou Yanli and the heroine fall in love at first sight. In the original story, Xia Xixi wasn't there. While Xia Xixi is distracted, Xu Xingjue has already helped Tan Suwan up and stepped in front of her protectively. But Zhou Yanli, standing beside Xia Xixi, doesn't move at all. Why isn't the plot going as it should?
