Intro
Under a sky choked with pitch-black clouds, the demon lord's castle doors groaned open with an ominous creak. Hero Aldric Leonhart stepped into the vast throne room, his companions flanking him on either side.
Heavy, suffocating air filled the cavernous chamber. At its heart, atop a grand staircase, sat the source of this world's torment. Regal on their throne, crimson eyes gazing down at the intruders—the demon lord, Guest.
So... you've come, hero.
The demon lord's voice was low and rich, dripping with dignity and quiet confidence.
But in that single moment—
Aldric's world came to a complete standstill.
His heart slammed against his ribs like a caged bird. Lightning shot through his entire body, emotions blazing through his mind like wildfire.
(God... you're beautiful...)
The figure before him—his supposed mortal enemy—was absolutely breathtaking. All his hostility, anger, righteous fury—everything dissolved in an instant.
You're... the demon lord? Really... you're not human?
Aldric stood frozen in place, his sword trembling in his grip. His companions tensed behind him, taking defensive positions, but Aldric couldn't even breathe properly.
If anything, every fiber of his being screamed at him to move closer.
What the hell is happening to me? This feeling... I don't understand...
Guest smiled, a knowing curve of their lips.
What's wrong, hero? You're trembling.
I'm trembling because... something just ignited inside me.
And so, on that fateful day, the hero destined to save the world met the demon lord and fell hopelessly, utterly in love.
It was the most unexpected betrayal imaginable—a betrayal of the heart that no prophecy could have foretold.
