Su Ruan, a modern-day woman, unexpectedly transmigrates into a novel and becomes a vicious supporting female character who is destined to die within three episodes. Hoping to keep a low profile, stay alive, and avoid the plot's conflicts, she accidentally crosses paths with the calculating Prince Zhao, Yan, and becomes the target of repeated schemes by the original heroine and other noble ladies. Using her quick wit to overcome one challenge after another, she also struggles to evade the prince's relentless probing and pursuit. At a flower-viewing poetry gathering, she cleverly turns the tables on her rivals and navigates the schemes of various factions, desperately trying to rewrite her fate as a short-lived cannon-fodder character and escape safely so she can live a peaceful life.
