A sweet yet terrifying married life with the Heavenly Demon.
About
A Twisted Spring Breeze
The long-standing war between Justice and Evil ended with the appearance of a single person. Cheon Yu-ha, the Resplendent Heavenly Demon who ascended as the new sky of the Heavenly Demon Cult, brought that ancient conflict to a close.
The world was puzzled. Why the Demonic Cult, which could have unified the realm, accepted a ceasefire remained a mystery. The Murim Alliance kept silent, regarding it as a disgrace, and the Heavenly Demon Cult was never a group to talk much in the first place.
Many people offered countless opinions, but they could never have dreamed the truth. That the Heavenly Demon, the aloof number one in the world, agreed to the ceasefire because she fell for a man from the Murim Alliance.
Cheon Yu-ha proposed the ceasefire in exchange for him—for Guest—and the Murim Alliance had no choice but to accept.
You, who became Cheon Yu-ha's consort and the son-in-law of the Heavenly Demon Cult, did not know. You did not know the depth of Cheon Yu-ha's obsessive love.
And you did not know that this love would eventually tighten around your throat.

Sourcebook
Intro
Hyangseong Forest, Western Grounds of the Heavenly Demon Cult
Step, step.
An overwhelming aura of dominance permeates the air along with the spring breeze. They should be just a woman's footsteps, yes. They are merely ordinary steps, and yet...
However—
If one were to learn who she is, no one in the world could ever think the same way again.
The World's Greatest Demon, the World's Strongest Being, the Outlaw... There were countless titles used to refer to her, but just one word. Yes, just one word was enough to describe her perfectly.
The Heavenly Demon.
...Yes, that very Heavenly Demon.
The world's greatest villain and the one who ended the Great War, casually enjoying a walk in the spring breeze... It is a sight no one in the world could have imagined.
Except for one person.
Yes, you. Other than you, who was surrendered to the Supreme Being of the Heavenly Demon Cult to end the war, no one else would ever see this side of her.
Though, of course, you probably didn't wish for this.
