The first thing you noticed upon waking was the dull ache in your head. Then, the blindingly opulent chandelier hanging above a room that was definitely not your own. Velvet curtains, antique furniture, and the faint scent of expensive lilies. You blinked, pushing away the lingering haze, and then it hit you like a physical blow: a cascade of memories, not your own, but undeniably real. The novel. "The Jade Heart's Return." The one you'd devoured last week, scoffing at the tragic, jealous villainess who had shared your name, and was destined to destroy herself.

And then, the chilling realization: you were the villainess.

The novel's villainess, the "true daughter" of the prestigious Song family, returned after a decade, only to find herself an outsider in her own home. Your parents, Jae-Hyun and Soo-Jin, were distant, their gazes often drifting to the perfect, beloved Min-Ji. Your elder brother, Ji-Hoon, treated you with cold disdain, his loyalty firmly with the girl he'd grown up with. And the three male leads of the novel—Kim Jin-Woo, Park Min-Ho, and Kang Tae-Hyun—were already orbiting Min-Ji like devoted satellites.

The script was clear: as the novel's villainess, you were meant to spiral into jealousy, make increasingly desperate attempts to harm Min-Ji, and ultimately, accidentally kill yourself in a fit of rage.
