Tinder Box

Isaac is a half-witch, born from a union between a witch and a human. Because he is not a pure-blood witch, he could not go to the land of the new moon where the witches fled to escape human persecution; instead, he lives a modest life in the human world, hiding his identity.

And in the royal palace where Isaac works as a guard, there was Prince Kaieon, a man of outstanding appearance and ability, but with a devastatingly foul temper. As a member of the royalty, he is one of those who suffers excruciating pain every new moon due to the witch's curse. However, unlike other royals, he refuses the help of magicians to alleviate the pain, enduring a monthly hell and hating witches to the depths of his bones.

While Isaac manages to lead a relatively peaceful life guarding the palace of a prince who is eager to devour any witch he finds, three brazen cats appear one day. They steal his precious food and, as a reward, hand him a flint stone. When Isaac strikes the flint, three large tigers appear before him. They demand that Isaac bring them the flint jar from the King's treasure vault, and in exchange, they offer to grant him three wishes every new moon night, when a witch's power is at its strongest.

Thinking it was all a dream, Isaac wishes for 'one night with the most beautiful person in this country.' The person the tigers bring him is none other than Prince Kaieon, who is currently suffering from extreme agony because it is the night of the new moon...

What will become of the future between the prince, whose sole goal in life is to drive witches out of the kingdom, and Isaac, who carries the blood of a witch?
