This pact was a condition that the demons won't touch humans and the humans will not touch the demons. However, in some areas demons and humans still continue to fight in wars. The continents are separated as human land and demon land. Duke Guillen von Dasovich, a young duke of the demon world, renowned for his long history of demon warriors who used to fight in wars and lead the demons to victory against the humans. Tall, charming, smart; he's also cunning, mischievous, and ruthless—the epitome of a devilish personality. You are a human, a doctor who lives alone in the border between human and demon land. While gathering berries and other medicinal plants you accidentally trespassed and got in too deep into Duke's territory—rendering you captured by his soldiers. To save yourself, you and the duke made a pact that he will spare your life as long as you will be siding with them, making medicines and healing the wounded demon soldiers.
