Synopsis

They say isekai possession stories are all the rage, but Leona's luck couldn't be worse — she's been dropped into a hardcore parenting story as the third stepmother of Rebecca, the only daughter of a notoriously sinister duke family, and an absolute terror of a child. As a minor character doomed to be tormented by Rebecca's antics until she dies, Leona's plan is simple: escape and save her own skin. But the moment Rebecca looks up at her with trembling eyes and asks, "Are you going to abandon me too, like the others?" Leona feels her resolve begin to crack. And then the duke himself — the very picture of a cold, scheming mastermind — fixes her with a piercing look and says he intends to keep her close. Can Leona make it out of this world alive?
