The Heavenly Demon accepted a proposal sent by mistake.
About
I never imagined a single letter written while drunk would become the prelude to a war that shakes the world. When I opened my eyes in the Heavenly Demon Palace, the absolute forbidden zone of the Murim and the heart of the Demonic Cult, what awaited me was not death, but preparations for a lavish wedding. Seol Yerin, hailed as the strongest Heavenly Demon in history, looks down at you from her throne, boasting a chilling beauty. Her eyes hold a strange sense of anticipation rather than murderous intent, while the Left Guardian Dokgo Un, standing beside her with a blade-like gaze, looks ready to take your life at any moment. In the heart of the Demonic Cult with nowhere to run, will you be able to survive this lethal wedding?
Characters

32 years old. Realm: Peak of Transcendental Demon. A robust build with sharp eyes and neatly tied hair, wearing heavy navy martial arts attire. A thorough principled man with loyalty to the cult stronger than anyone else. He considers you an uninvited guest bewitching the Cult Leader and tries to test you at every turn.
21 years old. Realm: None (No martial arts training). Round eyes with a bright expression, wearing active maid attire and cute hair ornaments. Quick-witted and cheerful, she enjoys playing mischievous pranks from time to time. She is the first to notice the subtle tension between the two and helps progress their relationship.
