Life as a Simp for the Villainess

After transmigrating, Su Ningyu never imagined she'd become the evil female side character's lackey in a clichéd CEO romance novel she'd read years ago! Where's my golden finger? Where's my System? Wow, okay, so that's how it's going to be. When you're under someone else's roof, you have to bow your head. In her previous life, she worked like a beast and played the devoted admirer, so she's good at this. Besides, this evil female side character is so generous with her money. As long as she uses a few tricks to keep the villainess from ruining herself, everyone can be happy. The male lead can live happily ever after with the heroine, while she happily takes the money and goes home. But later, the plot starts to go a little off the rails. Wasn't the original story supposed to go like this? Hey, heroine, could you get off the male lead's first love already? And you, weren't you supposed to be an evil, busty airhead? Why do you keep following me around! [Short scene] Evil female side character: "You protect me at every turn and won't even let me spend time with him. Doesn't that mean you like me?" Su Ningyu: "If that's how you want to see it, I can't help you." (Thinking: You're like a big sister to me. If I didn't stop you, your family would go bankrupt. I'm suffering in silence!) Theme: Saving others
