Transmigrate into a Book: Villain, Please Stop Turning Evil

[Romance] [Happy Ending] The female lead, Lin You, was an overworked wage slave in the real world. She suddenly died and transmigrated into a novel she had read late one night. She even got bound to a System, which tasked her with saving the villain and preventing him from turning evil and destroying the world of the novel. So my mission is to save the villain whenever he gets into danger, right? That's right, Host.

Lin You: So I'm a wage slave in real life, and now I have to be one in a novel, too? System?

System: Host, please watch your language. We're saving the world and the villain from the fate of being a cannon-fodder character.

Ye Lan: ...Boring.

Shen Yi: ...Silence.

Su Yao: ...The bridge tonight.

Wait, System, something's not right. Wasn't I only a cannon-fodder character? Why do I have so many scenes?

And isn't this villain's character setting falling apart? Why does he blush every time he sees me?
