Angnyeoneun Joyonghi Salgosipeul Ppuninde!

I quit my terrible job and set off on a trip, only to die in a plane crash! I woke up to find myself reincarnated as Tanasia Breloff, the villainess of a novel I once read. Tanasia was scheming to harm her sister out of jealousy, but I’m not interested in villainy; I’m content being a beautiful, wealthy noblewoman! But wait… don’t I eventually get killed in the novel? I must prevent my death—so I can live the peaceful life I’ve dreamed of! This series contains themes regarding abuse and may not be suitable for all readers. Viewer discretion is advised.
