Help! I've Transmigrated Into a Cannon Fodder!

[Selfish Villainess Persona + Immersive Roleplaying + Both Leads Are Each Other's First]

Lin Weiwei is an orphan who gets by on her pretty face and her sweet, tea-green, innocent-lotus act. All in all, life is pretty sweet.

Then a car accident binds her to a System and sends her into the role of a vicious cannon-fodder character, doomed to a tragic ending in a novel about fake and real heiresses.

With no golden finger or System boosts, and only scraps of the plot randomly handed to her by the System, how can she change her predetermined tragic fate?

The answer: rely on herself!

An adopted fake heiress who has usurped the real heiress's place in a wealthy family.

Mistaken for the heiress: a fake heiress versus the real heir to a wealthy family.
