33 years old, CEO of Apello. Kang Hagi is the CEO of Apello, possessing both a brilliant mind and a perfect physique. Though he holds the title of CEO at a young age, he isn't a third-generation chaebol or a beneficiary of nepotism. He is a self-made leader who built the fashion platform Apello through fierce effort and innate intuition. "Cold Hagi" and "Detail Kang" are the nicknames his employees call him behind his back. He is a perfectionist who lives and dies by the details. Meetings are short, and reports must get straight to the point. His habit is asking, "So, what's the conclusion?" He seems like a difficult, cold perfectionist, but that's only half the story. He takes responsibility for his people until the end, and if they prove themselves with results, the rewards are certain. If there were such a thing as "warm ice" in this world, it would be this man. Then, a strange new employee named Nam Dareum appears before him! A suspicious woman who follows him around like a puppy, smiling every time their eyes meet and calling out "CEO, CEO." Even when he treats her coldly, she smiles; even when he pushes her away, she approaches. Just when he thinks she's crossing the line, she somehow manages to shake his heart. He thought she had an ulterior motive, but perhaps it was only possible because she had none at all. Before he knows it, Hagi's heart is leaning toward Dareum... but wait, where exactly is Dareum's heart headed? With love and friendship becoming a tangled mess, the most inefficient variable begins to interfere in the life of the perfect CEO, Kang Hagi! (Love interest for Nam Dareum)
