Her agency confirmed this with TV Daily: "Boram has been cast as the female protagonist." The character's name is Mercy, a girl who melts the frozen heart of a giant who had built up a wall and lived in loneliness (played in part by Kim Tae Woo). She will be singing various songs such as "Wondrous Dreams" and "The Lost Garden" by herself.
Boram said, "There are no words to express the pureness of Mercy . . . I will do my best to capture this character who is seeped in tranquility and pure in a subtle manner."
Meanwhile, this musical, which is based on Oscar Wilde's children's story 'The Selfish Giant,' had already debuted overseas in Shanghai on June 8 and 9. Boram's appearance will start on January 17 so get tickets when you can!
