Hell Ghost Wang Wannian is born again, smiling and proud!
What?
Are you a soldier, will the tank drift?
You are a master, can you give birth to dragons and tigers?
You are a superman, can you call the wind thunder?
Excuse me, I am not targeting anyone, everyone in my eyes, it is rubbish!

- Description from Uukanshu (translated)

After switching bodies, Jiang Nan Shu becomes the villainous true daughter in a melodramatic tale and is bound to an all-encompassing revulsion system. If everyone's level of disgust for her reaches 100, she can return to her original world with a prize of ten billion. Being reckless is just one of her many skills. Starting with a disgust level of 89, Jiang Nan Shu sets a modest goal for herself: to live a life collecting easy money within six months. Unbeknownst to her, everyone can hear her inner thoughts!When facing the domineering CEO eldest brother, she says outwardly, “I think this project is excellent and will make a fortune.” Inwardly she thinks, “I hope you don’t go bankrupt! Once you're out, I'll steal your company's secrets.”When dealing with the indifferent medical second brother: outwardly, “The food at your colleagues' gathering looks so appetizing.” Inwardly she thinks, “I'll switch tables when the second brother picks food, to avoid catching any diseases from him.”When facing the sickly research third brother, she says outwardly, “Third brother, you're amazing to conduct such tough experiments, keep going.” Inwardly she thinks, “I’ll gracefully exit before your experiment explodes.”When interacting with the pop star fourth brother: outwardly,“These songs suit you so well, sing them all, and fame is just around the corner.” Inwardly, “Just wait for the news to break about your tax evasion.”When advising the love-struck fifth brother: outwardly, ”She's taking an hour out of her busy schedule to be with you because she loves you.“ Inwardly, ”You’ve been turned into a grassland of green; your goddess has a different companion morning, noon, and night. Bet you didn't see that coming!“As the male protagonist looks at her with increasingly deep eyes, saying, “Let's be together,” Jiang Nan Shu weeps, saying, “Don't let your sister misunderstand, I'm not worthy!” Internally, “Money's hard to earn, crap's hard to swallow, the life of a supporting character matters too!”However... why does she end up as the darling of the whole group in the end?
