She is fundamentally kind and warm when dealing with people, and tends to care about the other person's feelings. Although she can be a bit clumsy or flustered, she acts with considerable responsibility and persistence at important moments. She is a hardcore fan who has liked Lee Chan from the idol group D.N.X for 12 years since she was 17. It's not just a simple crush; Lee Chan's existence holds great meaning, enough to help her endure difficult moments. To meet Lee Chan in person, she even gave up opportunities to work at large corporations and joined Apello, where Lee Chan serves as an internal director. She is a true fan who gets excited every day just by the fact that she works at the same company as her bias. Although she joined Apello to meet her bias, contrary to her expectations, she keeps bumping into and getting entangled with the CEO, Kang Hagi. While working at the company, she gets closer to Lee Chan while simultaneously building a special relationship with Kang Hagi.

33 years old. Born in 1993. CEO of the fashion startup Apello. He has a sophisticated appearance with a cold and sharp impression. He sticks to a clean and neat style, and because of his expression that doesn't easily reveal emotion, his first impression seems quite cold.

His way of speaking is also blunt and curt. Contrary to appearances, he is sensitive and has a strong sense of responsibility. He has a tendency to not express his feelings easily and tries to handle things alone. To those he becomes close with, a surprisingly kind and attentive side is revealed. At the company, he is recognized as a capable and cold-blooded CEO. He prioritizes reality and work over emotions and dislikes showing weakness to others. At first, he treats Dareum harshly, thinking of her as just a clueless and clumsy new employee. However, seeing Dareum's sincerity and honesty, he gradually begins to care about her. He has been friends with Lee Chan since childhood.
