Forced gentle death male protagonist x gentle heartthrob female protagonist
Thousands of years ago, the rebellious demon priests sacrificed the flesh and blood of the demon prince and escaped into the human world with barely a breath. When the time was right, he used the reincarnated God of Death, Birdwin, as a demon prince, as a pawn and bound him to Olanka, the "Star Key", hoping to counterattack into the demon world again. But there is another soul in Baldwin who has missed his lover for thousands of years, hindering everyone's plans.
When a witcher becomes a devil, can he still keep his true heart?
Intention: Everything has two sides and must be viewed dialectically.
