No matter how much she likes him, she must never have sex with Akisame.

Yukika is a former Japanese person who has been reincarnated as the villainous princess in the novel "The Legend of the Lotus Flower Under the Moon."
In the story, Yukika is set to marry Enrai, the young king of the Land of Yo-no-kuni, who turns out to be the final boss, but she is obsessed with her sister's husband
, Akisame. She kills her own sister and takes Akisame to her new home as if she were her servant, indulging in an affair.
This incurs Enrai's wrath, leading to his condemnation and the start of a war.

That future is absolutely unacceptable!
So she distances herself from Akisame. That's what she thought she had resolved to do.
Perhaps due to the coercion of the scenario, her sister is poisoned by someone.
Then, just when it seems Akisame follows her to her new home of her own accord, he forcibly opens his body to her.

Meanwhile, Enrai, who had seen through everything,
teases Akisame as if he had found an interesting toy, and leads her to develop Yukika's body...?
