Outer World, the last work of Doosan Humanities Theater 2015, tells stories about Hiki Komori and Tomio, who is a counselor of a group assisting Hiki Komori, as well as stories about their families. It was a great hit in Japan because Hideto Iwai, who received the Mukoda Play Award for his TV drama screenplay and the Kishida Play Award for his play scenario, wrote and directed the play and acted in the play. Park, Geunhyeong, who won the best picture award at the 2010 Korea Play Award for No Sleepless Night, directs the play.
