Wen Chu, a socially anxious homebody, wakes up one day inside a novel as the male lead Xi Liye's doomed ex-girlfriend, a cannon-fodder character he will eventually settle scores with. To survive, she decides to take the initiative and drive him away by playing the role of an impossibly demanding girlfriend—bombarding him with messages, clinging to him affectionately, and constantly making a fuss, all in the hope that he will be the one to ask for a breakup. But she never expects Xi Liye, rumored to be a cold, ruthless campus prodigy with an extreme sense of boundaries, not only to stay but to become increasingly indulgent and obsessed with her. She thinks she is desperately trying to save herself, unaware that he has had his eyes on her ever since their accidental relationship began. The more she wants to break up, the more tightly he clings to her; the harder she tries to escape, the deeper she falls.
