Two women, one-on-one.
Jiuyuan Nai is the finest etiquette tutor among humans.
Two years ago, she made a verbal agreement with the Demon King: once the demon princess turned eighteen, she could leave the Demon Capital and return to the human world.
And today is precisely Lily's eighteenth birthday party.
But Lily has forcibly kept Naina by her side.
By demon custom, Naina is the one Lily has chosen as her beloved.
That's how the demon world is: free and unconstrained. A demon princess can do whatever she pleases.
She can fall for a girl, even if that girl isn't a demon.
"Your Highness! That isn't the right position, is it? The manual doesn't say to do it like that!"
Demons and humans are natural enemies,
but to Lily, that simply doesn't matter!
"Naina! I've set my sights on you! You dare disobey me?"
Being overbearing isn't just a way to conquer the world,
it's also a shortcut to winning the heart of the one you love.
