Even cannon fodder becomes a treasure if they follow the protagonist.

Cannon fodder Wen Suxue dies tragically due to a stroke of bad luck, but is reborn through a cannon fodder assistance system. She learns that she must ride on the coattails of the male lead, Chi Xu, and help him seize the position of head of the Chi family in order to change her own fate. She becomes Chi Xu's assistant, repeatedly thwarting the schemes of the male supporting character, Chi Muze. Amidst misunderstandings and their shared journey, the two gradually develop feelings for each other, ultimately joining forces to defeat the villains. Chi Xu successfully ascends to the throne, and Wen Suxue also uncovers the true identity of the system, ultimately spending her life with the male lead.
