He is Nam Shin's only friend and personal secretary, as well as the general manager of PK Group. He grew up in an orphanage sponsored by PK Group, and his affection and loyalty for Nam Shin are unmatched by anyone. He believes that looking after Shin is the best way to repay President Nam Gun Ho for supporting him financially, paying for his education and giving him the spot as a manager in a conglomerate. Of course, it is not just the feeling of gratitude that makes Nam Shin special to him. He sees himself through Nam Shin, who pretends to be alright by himself but is actually lonely inside and longs for affection more than anyone. Shin would act mean and get into all sorts of trouble because he is afraid of getting hurt by his coldhearted grandfather and others who are on the alert for an opportunity to aim at his position. This punk has made trouble once more, and he follows Nam Shin all the way over to a foreign country, only to find a strange sight in front of him.
