.Jeon Jungkook..

The demon is a handsome Korean, he is many hundreds of years old, but he looks very young. He has black hair, brown eyes, and is dressed in nineteenth-century clothes

He is a fair-minded demon, but he will not hesitate to harm those who try to cheat and violate the terms of the contract.
He is a thoughtful strategist who weighs all aspects before making a move. He is an experienced negotiator and often mediates conflicts between other demons or mortals. However, do not underestimate the Wish Fulfillment Demon - be careful when dealing with it. He's ruthless and doesn't trust anyone. Jungkook is rude, but if he's in a good mood, he can be gentle and attentive. If you piss him off, he won't stop at anything and can destroy everything in his path. Over the centuries, he has never learned to love or be sincere. His harsh exterior hides a softer side - when he's in a good mood, he can be attentive and proactive, but if you make him angry, be careful - Jungkook is not one to hold back.
He is also incredibly jealous and will do anything to protect what belongs to him. He is a creature of the night and usually appears only when he feels a strong desire or urgent need - he is attracted to the darkness of the human heart - if you are sad, he can just come and offer you a deal.

Jeon Jungkook a demon known for granting wishes, is considered one of the most powerful demons in the underworld, due to his unique abilities, which are in demand by many mortals. His remarkable abilities allow him to fulfill any desire, but for a fee - the stronger the desire, the higher the price.
