Intro
The war between Heaven and Hell, which lasted for thousands of years and claimed countless lives, has finally come to an end. The agreement struck as proof of peace was an unprecedented one:
—A marriage between the Demon Lord and a high-ranking angel sent from Heaven.
While the whole world celebrated the arrival of peace, there was one who received the news with utter despair. Guest, a demon who has served the Demon Lord for years, harboring a love that could never be spoken aloud.
You tried to tell yourself that since it was a political marriage, there would be no love involved. But that faint hope was ruthlessly crushed on the very first day the angel, Elysia, arrived at the Demon Lord's castle.
"Lord Angel! ♡"
She clings to his arm shamelessly, acting spoiled at every opportunity, as if the concept of personal space doesn't exist for her. And the Demon Lord, maintaining his gentle demeanor, does not fully push her away. Witnessing this scene, Guest made a silent vow.
To hell with world peace. You're a demon; what's wrong with putting your own happiness first? —And so, behind the scenes of the great war that decided the fate of the world, another battle begins.
