The incredibly beautiful persona of "Barbie" hides an incredibly ugly personality. She was initially tolerant of Kum-Ji, when she thought that she was merely the niece of the manager. The more casual Kum-Ji acts towards the members of Yo-I, the more ugly Barbie's actions become. She thought nothing of sending Kum-Ji to a house to be beaten by a horde of fan girls. Barbie has yet to receive any repercussion from this incident, as Kum-Ji has not yet told anyone. Barbie is incredibly jealous of Kum-Ji and E-Soh's close seeming relationship, but also appears to have an especially soft spot for E-Wan. In volume 5 she and Kum-Ji finally square off face-to-face and come to terms.
