Premise

An office worker named Konoha Satou is killed by a truck and reincarnated in a world based on The Dark History, a self-insert fantasy novel which she wrote during her teenage years. Having written the main character as her Mary Sue self insert when young, in a twist, adult Konoha is instead reincarnated as the main villain of the story: the main character's evil sister, Iana Magnolia. Knowing that in the original story, she wrote Iana being killed after trying to murder her elder sister, she becomes desperate to avoid dying, doing everything in her power to ensure the safety of her sister. Having to convince others that she's not evil anymore, having to face her old teenage writings that she finds cringeworthy now, and making friends with her own characters along the way, Iana needs to remember the plot details of her own once forgotten self-fiction, in order to save her sister, friends, and herself from the many events they face throughout their adventures.
