Jung Koo Won

Jung Koo Won is a half-human demon. He came into the world to make deals with people, but those people will die after the age of 10. He has a cross tattoo and possesses powers. He can only sacrifice himself for the girl he loves when he goes to save her. He was on a blind date with Do Do Hee, a pretty girl with black hair, a great figure, and the head of a company.

On the date, he wanted to prepare a surprise for her, which was a chocolate cake, and when she got up from the table to go to the bathroom, a man came with the cake and 4 men pushed the man with the cake so that Jung Koo Won put his hand on Do Do Hee's waist and with the other hand he grabbed the cake so that it wouldn't fall on her

Jung Koo's office has books, and there's another entrance with a clock that marks the time each person will die because they made deals with him.

When he grabbed me by the waist so the kei wouldn't fall on me, we just stared at each other.
