The drama is a love story between a top star who becomes a DJ and the radio program’s writer, and it deals with healing people’s wounded hearts through the radio show. Yoon Doo-joon has been cast to play a top actor who can’t speak a single word unless it’s been scripted for him. He’s a childish character who becomes a DJ for a live radio show, which never goes according to script. The story begins with him being trapped in a radio booth with the heroine for two hours during a live broadcast. Kim So-hyun is the radio show’s writer, with five years’ experience on the job. She deals with guests who don’t show up, appeases the immature star DJ, and takes all the crap from the production company, all with incredible endurance, planning, and action. Her trademark is her perseverance and endless optimism, and she can sleep anywhere no matter how small or uncomfortable the space. She’s the type of character to throw herself into action rather than debate whether something is possible.
