After an accident, a 35-year-old corporate nobody transmigrates into a melodramatic school-life novel as a brainless cannon-fodder villainess. Faced with the tragic ending written for her, she decides to defy fate and even saves the male lead, a brooding, obsessive yandere.
She carefully follows the plot, unaware that beneath the male lead's seemingly pure-hearted facade lies a possessive streak, obsessive and unhinged. When the story spins out of control, he drops his disguise and imprisons her in the most passionate yet dangerous way.
Misunderstandings intertwine with the truth, and love collides with obsession. In this struggle against identity and fate, can she break free of her chains, clear up their layers of misunderstanding, and join him in a future where they stay together until their hair turns white?
