The Man Who Laughs (웃는 남자) is a Korean original musical based on Victor Hugo’s novel of the same name. The story centers on Gwynplaine, a young man disfigured as a child, his face surgically altered into a permanent smile by comprachicos (child traffickers), under orders from powerful aristocrats. Abandoned soon after, he is discovered and taken in by Ursus, a philosopher and traveling performer who becomes a father figure to him. Together with Dea, a blind girl also rescued by Ursus, they form a makeshift family and earn their living through performances that capitalize on Gwynplaine’s unique appearance.

Throughout the story, Gwynplaine forms a close bond with Dea, a blind girl who values him for his character rather than his appearance. He later discovers that he is the rightful heir to a noble family, leading him to confront the contrast between the privileged world of the aristocracy and the struggles of the lower classes. His newfound status brings him into contact with Josiana, a duchess who expresses a complex mix of fascination and disdain toward him. Meanwhile, Barkilphedro, a court jester, manipulates events for his own benefit, adding further tension to Gwynplaine’s journey.

The musical features a score by Frank Wildhorn and explores themes such as identity, social hierarchy, and morality. Incorporating gothic visual elements and moments of emotional depth, The Man Who Laughs has been recognized for its unique storytelling and its contribution to the landscape of Korean musical theater.
