A Small Shop for Salted Fish in the End of the World

[Apocalypse + System + Space + Management + No Romance + Relaxing] A lazy bum named Shi Sui wakes up to find herself transmigrated into a post-apocalyptic novel, as the villainous female supporting character. System: Please run a shop in the apocalypse; a life of leisure is not a dream. Shi Sui, who has worked diligently for eighteen years, suddenly perks up. Since she's already here, she might as well have some fun. Premium boxed lunches, fun snacks, strange props, a sweet treat zone, a street full of snacks, and exciting action scenes... There's nothing Shi Sui can't imagine, and the system can't provide. Shi Sui leisurely runs her shop, occasionally tending to flowers, enjoying a peaceful life. But there are always those who are blind and cause trouble. So be it. Shi Sui: (Smiling face) Block and throw them out. They can't be in her shop anywhere. Halfway through, Shi Sui realizes something's wrong. Is the script she knows too outdated? Where did this woman, even more dazzling than the female lead, come from? System: Guilty, but I won't say.
