Nachal is one of the main characters of Gwisin Byeolgok
He is selfish and greedy at first, but as the series goes on he shows his more responsible and perhaps a little caring side. He tried to take over Ahryung's body, but he got beaten back, and from that he learned to respect her, although he wouldn't ever tell that to her.
He used to be a normal kid with a brother, a younger and a older sister, but one day the brother died. He had gone off wearing black clothing and promised to return to his siblings, even if he died. He had killed his boss (?) and was just about to return to his family when someone else ran him through with a knife.
And so he couldn't properly "die" because of not his grudge, but his siblings promise that they would wait forever. Until he got to them and set them free, he had to live and also had to have a strong contractor to help him along that way.
And then he met Cheo Yeon and her extraordinarily strong daughter.
