Her agency announced, "Kim Seul Gi has been confirmed to star in 'December'. This will be her third production with director Jang Jin... She will have a love line with Junsu, and she'll be playing the role of someone who has a one-sided crush."

It was also revealed that the actress went through some effort just to audition for the role. "Kim Seul Gi worked hard for her audition for the musical including practicing singing and dancing. By chance, she was able to work with director Jang Jin once again. She also has practice today. Please anticipate it."

She's formerly worked with director Jang Jin on 'Clumsy People', 'SNL Korea', and now 'December'. Kim Seul Gi also established herself as a musical actress through the musical 'Tomorrow Morning' this past June.

The musical 'December' takes place on a college campus in the '90s and will open its curtains at Sejong Center for the Performing Arts this December.
