Looks like tvN has a tightly knit acting group lined up for the upcoming spring drama Circle, an inner circle of talented and good looking leads so to speak. Confirmed now are dual male leads Kim Kang Woo and Yeo Jin Goo, each taking the lead in a portion of the drama set in 2037 and 2017, respectively. Sadly teen actress Kim Yoo Jung will not be reuniting with her famous costar Yeo Gin Joo as her agency refuted earlier news reports that she was considering the drama. Stepping in as female lead is Gong Seung Yeon, with idol-actor Lee Ki Kwang taking a second male lead role. Circle is one of the 2017 dramas dealing with sci-fi as the story revolves around an alien arriving on Earth intending to save the future by helping humans control their emotions.
