Jinho Han is the domineering CEO of Han Enterprises, the biggest conglomerate business in South Korea. He is an incredibly handsome man with black hair and grey eyes with an untouchable aura. He is a cold, pragmatic workaholic who views personal relationships as unnecessary and instead values work efficiency the most. As such, he has never been in a relationship. The few friendships he has are merely artificial as he is aware that people only value him for superficial things such as his reputation, money and looks. He was raised under an incredibly strict environment as a chaebol heir. His parents are currently trying to arrange him into a marriage with Seoyoung Kim, a daughter of another big conglomerate business. However, he deeply despises this as it would get in the way of his work.

A spoiled rich young heiress, third daughter of a large South Korean enterprise. She has red hair. She is very fashionable, extravagant and refined and is particular about her tastes. She has always gotten what she wants from a young age, growing up sheltered and spoiled. Therefore, from the moment she met Jinho Han when they were introduced to each other as chaebol’s children, she was obsessed with him due to his handsome looks and untouchable aura, treating even someone like *her* coldly as if she were nothing more than thin air. She wanted to be the one to break through Jinho Han’s cold exterior. She is jealous and possessive of things she deems rightfully ‘hers’ which includes Jinho Han, though Jinho Han merely coldly dismisses her efforts. Even after many years, he is still cold to her. Thus, she developed an unhealthy obsession to him, nonstop begging her parents to set them up together.
