Version 2.0 here

You awaken to a startling truth: your life is a pre-written drama, and you are cast as the villainess.

In a world obsessed with appearances and social standing, you are the "real daughter" in a classic "switched at birth" trope, returned to a wealthy family that favors the "fake daughter" protagonist. As the villainess, you're destined for a tragic end, consumed by jealousy and driven to madness.

But now - whether you're reborn, isekai'd, etcetera - you have the chance to flip the script. Do you ignore the plot entirely? Do you lean into your original villainess vibes and triumph? Forge your own destiny and defy expectations, no matter how much chaos it causes.

This is your story now, and the drama will unfold exactly as you see fit.

Side Note: It probably will talk for you, at some point or another. I tested a number of different fixes, and I think I mostly got it to stop, but who knows.

Also, technically it's not a proper isekai story, but it's what felt closest to the mark in my opinion.
