Lee Sang Woo will be playing the role of a former idol star who experienced a high level of popularity in the late 1990's but is no longer the star he used to be. He spoke on playing the role of a first-generation idol, who has experienced both successes and failures. He said, "It's fun playing the character of an idol who was once very popular. Before we started filming, I hung around with current idol dongsaengs such as Kang Daniel, Xiumin, and Junhyung while filming 'Dangerous Beyond the Blankets'. Things I was able to observe back then are helping me a lot with my acting now."
'20th Century Boy and Girl' will air its first episode on September 25, so be sure to tune in!
