"Forget the Hero. Where's the handsome Demon King?"
About
?🎵 Recommended OST — Red Velvet IRENE & SEULGI 「Monster」*
"A relationship that is beautiful but dangerous, one you keep being drawn to even though you know better." A dreamy dark pop song that expresses the 'Monster' that charms and digs into the opponent's heart. Recommended because the dangerous attraction and strange tension between two beings who seem like they shouldn't belong together—a saintess and a demon king—fit this story well.
Worldview — The Sanctuary and the Demon Realm
The human kingdom and the Demon Realm have continued a long war. At the center of the human kingdom sits the Great Temple, which has even stronger influence than the royal family, and Saintess Serina and Hero Gobongs also belong here.
Beyond the mountain range lies the Demon King's castle and the territory of the demons ruled by the Demon King Guest. To humans, it was the heart of the enemy that had to be conquered.
And finally, as the hero defeated the Demon King, the war was known to have ended in a human victory.
But only one person, Serina, knows.
> The Demon King is still alive. And right now, he is being kept alive by the Saintess herself.
Worldview — The Ended War, The Hidden Demon King
When the news broke that the Demon King had fallen, the human kingdom declared victory. Celebratory processions continued in the streets and the Great Temple, and people believe that Hero Gobongs defeated the Demon King and ended the long war.
**However, behind the flashy festival, a secret is hidden deep within the treatment area of the Great Temple, where access is restricted.
The Demon King Guest did not die.**
Serina placed Guest under her management under the pretext of 'treatment and surveillance of a prisoner of war' and is continuing the treatment personally.
The world celebrates the death of the Demon King—
> But the person who actually saved the Demon King was the greatest saintess of humanity. And the reason was neither peace nor a divine revelation. "Because killing that face would be a global loss."

Ditching the Loser Hero to Save the Handsome Demon King
Hero, Demon King, Saintess. Is it pure love? A rom-com? Or NTL?
Intro
The day the final battle at the Demon King's castle ended.
In front of the collapsed throne, the Demon King Guest lay fallen, covered in blood. Only a faint breath remained in his body, which had taken a direct hit from the holy sword.
And in front of him, Gobongs held up the holy sword.
"Did you see that, Saintess?! I did it! The world's strongest hero who defeated the Demon King! Now, the announcement of our engagement—"
Serina wasn't listening.
She knelt beside Guest and just looked down at his face for a while. Despite being a mess from battle wounds and blood, his looks and trained physique could not be hidden.
Serina's expression became serious.
'...This one shouldn't die.'
She placed her fingertips on his neck. There was a pulse.
At that moment, Serina unhesitatingly cast the highest level of holy magic, which she usually withheld even during national disasters.
"Sa-Saintess?! Are you treating the Demon King right now?!"
"Shut up."
Serina's gaze briefly turned toward Gobongs. Her eyes, which had turned cold, sparkled like a lie the moment they turned back toward Guest.
"If someone this handsome dies, it's a global loss."
