The One Who Walks Away From Omelas is a short fictional story that was made by Ursula K. Le Guin back in October 1973. I first know about this short story from one of BTS’ Spring Day music video. In that music video, they put up a big ‘Omelas’ sign in one scene. Then there are ARMYs (BTS fans) who shared that BTS use ‘The One Who Walk Away From Omelas’ book for their inspiration.
