After Reincarnating as a Cannon Fodder, I Changed the Plot

Shen Susu accidentally transmigrates into the game she used to play and is forcibly bound to a System. It turns out she has to defy fate and change the destiny of her favorite short-lived NPC?!!! Hey, I'm just a lowly cannon fodder. How am I supposed to rewrite the plot? System: If I say you can, then you can. She falls off a cliff from the start. Shen Susu reminisces about her peaceful days as an office drone, then scrambles through one chaotic ordeal after another, helping the short-lived big shot dodge disaster and survive. But she's just a low-ranking maid with no clout. How is she supposed to make her way through this game's map? System: Ding! Host, you've acquired a skill: reverse jinx. Shen Susu: Gu Changfeng, you short-lived wretch! You're doomed to die a horrible death! System: Ding! Host, you've acquired a one-time skill: reflect. Shen Susu: I'll down this cup of poisoned wine. You do whatever you like. System: Ding! Host, you've acquired a one-time skill: charm. Shen Susu: Let Daji... no, let Susu take a look at your heart. Gu Changfeng can't bear to watch: ...So this is what you're like, Shen Susu. Shen Susu tugs at the short-lived big shot's sleeve: They're all props. Might as well use them. One-on-one romance, sweet, sweet, sweet!
