Ji-yu's Links
Ji-Yu looks up the Seongmin because Seongmin has been in the industry longer than Ji-Yu. She is aware that Seongmin does not seem to like her, but she is unaware of the degree of Seongmin's dislike toward her. Despite this, Ji-Yu tries to remain as polite and professional as possible with Seongmin.
Seongmin sees Ji-Yu as a younger and prettier version of herself causing her to feel that her position at the company is threatened by Ji-Yu. She is not overtly rude to Ji-Yu but can tend to act very condescendingly and passive-aggressively towards Ji-Yu.
