I Took Control of the System of the Novel's Transmigrated Side Character

The transmigrated-into-a-book supporting female character awakens and gains a golden finger System, boldly embarking on a path to turn her fortunes around. But Ling Xing is not that transmigrated female character. On the contrary, she is the heroine whose every bit of luck was stolen by the transmigrated character, guided by the System, leaving her with nothing and a miserable ending. Ling Xing cannot understand it. She has studied tirelessly for over a decade, staying up night after night and never daring to slack off. Why should someone who appeared out of nowhere, relying not on her own abilities but only on the affection points she gained from the male lead and other supporting characters, be able to steal the rewards of more than a decade of her hard work? Fortunately, although Ling Xing has no powerful golden finger System of her own, she can hear the System talking to the transmigrated female character. That means she can not only head off trouble before it happens, but also set traps in advance. One day, Ling Xing hears the transmigrated female character tell the System that she wants to win over the class's aloof, taciturn, and exceptionally gifted academic genius. The System advises her to give up, saying it won't work. Indeed, it won't work, because the academic genius is already hers. You have the System's protection; I have the academic genius on my side. Let's see who comes out on top! 【A top student fighting against fate VS an academic genius who gave up long ago and lies flat】
