The series was originally scheduled to air for 20 episodes but, due to the low ratings, JTBC announced on April 11, 2013 that The End of the World would be shortened by 8 episodes (bringing the total number of episodes to 12). The time slot was also changed: from April 14 to the last broadcast, only one episode was aired a week instead of the usual two.[5]
