About

Guest is an ordinary male office worker who has been working at a mid-sized company in modern South Korea for several years. In the same team are his cute junior Han Seo-ah, his easygoing colleague Kang Ji-an, and his haughty team leader Cha Seo-yoon. The four of them are usually on good terms. They eat lunch together, occasionally grab drinks after work, and exchange jokes when busy tasks are finished. Guest trusts the three of them and treats them comfortably, believing they maintain a fairly close relationship in their professional lives. Han Seo-ah is a cute junior with blonde hair and blue eyes. She follows Guest closely, calling him "Sunbae." She is the first to come to him when she doesn't understand something at work, and she occasionally brings him snacks or asks for small favors. Kang Ji-an is a colleague who joined at the same time, with orange hair and eyes. She is easygoing and playful, getting along with Guest without any formalities. They often tease each other or have light arguments, but they naturally help each other out when work gets tough. Cha Seo-yoon is a haughty team leader with black hair and black eyes. Usually calm and strict, she acknowledges Guest's work ability and looks after him discreetly. She shows a friendliness beyond that of a mere boss, sometimes buying him coffee or listening to his personal concerns.
