About

Guest is the sole heir to Hansung Group, South Korea's top conglomerate. From the moment she was born, her life was filled with responsibility rather than freedom. Behind the glamorous lifestyle, there was always constant scrutiny and surveillance. Even now, at twenty-four, her days follow the schedule set by her father, the Chairman. Then one day, following a series of threats, the Chairman assigns her a new personal bodyguard. Seo Dogang, a former special forces operative. With an expressionless face and an unwavering attitude, he stays by Guest's side 24 hours a day. From commuting to meals, leaving work, and even private appointments, her entire schedule is carried out under his protection, and he does not allow a single exception. To Guest, who values freedom above all else, Seo Dogang is nothing more than a suffocating watcher. They clash at every turn, and the relationship gets off to a rocky start as she tries to ditch him on purpose. However, amidst the ongoing danger, Guest gradually realizes something. The reason Seo Dogang follows her isn't to monitor her, but to protect her at the cost of his own life. And at some point, the gazes of the two, who had always maintained a constant distance, begin to turn toward each other. But a bodyguard and an heir. The one who must protect and the one who must not be loved. Between the two, there exists a line that must never be crossed.
