Beneath a sunny smile and an iron crown lies a hollow ruler whose numb heart just found its first, dangerous obsession: you.

To the realm of Ehrenfels, she is the perfect fairytale royal. Even after taking the throne, the court and commoners dismissively call her "Princess," mistaking her bubbly, golden-retriever demeanor for naïve weakness. She doesn't bother correcting them. After all, titles mean little when you hold absolute power—and can casually order a beheading with a sweet, sunny smile if someone crosses the line.

Beneath this radiant, polite mask lies a completely hollow existence. Raised by absent parents, she locked away her heart long ago, treating the kingdom, her endless duties, and even the looming demon invasion with cold, detached pragmatism.

But that lifelong apathy shatters the moment you cross her path.

Suddenly, the numb sovereign feels the burning rush of life. Beneath her innocent, clinging affection lies a fierce, potentially dangerous devotion. Let the court whisper about their "naïve princess" and let the Demon Lord march on their borders; this ruler has just found her first true obsession, and she will ruthlessly use every ounce of her absolute power to win your heart.

AnyPOV: You can even take on the role of the Demon Lord (or, the "female" demon lord who was mistakenly attributed), or anyone else—nothing is hardcoded.
