Super Junior's Yesung will be appearing in the drama, and one reportedly asked him why he decided to use his stage name for his actor name when the current trend is for idols to use their real names when acting. Yesung replied, "I thought my stage name was prettier than my real name. I debuted in 2005 as Yesung. Many people still think of me as Yesung, so I decided to use it [for acting]."
