Yu Zhixia unexpectedly awakens to the truth that her older brother, Yu Xingche, is destined to be gradually ruined by Shen Wantang, who uses favors and manipulation to bring him down, ultimately leading to his death. Given a second chance, she pretends to be an obsessive, clingy little sister who cannot live without her brother. She forces him to withdraw from the competition, exposes Shen Wantang's seemingly gentle manipulation, and cuts off her future connections before she can exploit them. Bo Yan appears cold and indifferent, yet always quietly has her back. The sudden appearance of a mysterious "Progress: 30" in Lin Zhi's mind makes the truth about this world even more puzzling. She thinks she is rewriting the ending, unaware that someone has been watching her from the shadows for years.
