Based on a witty and imaginative comic, this 2D animation captures the fun of manga and analog sensibility. Using the legendary hero character 'Chon Woochi', most popular among children and featured in TV dramas, movies, and books, along with the ever-popular theme of 'time travel' that best captures imagination, this TV special was produced as a follow-up to the 2015 theatrical film. It consists of 7 episodes: the modern part where Chon Woochi and Seok solve incidents in the present, and the past part that, as a kind of prequel, depicts the background of the confrontation between Chon Woochi and the King.
