First off - kudos to the brilliant writing in this script because it boldly holds a mirror to global society and there is not one filter used to make it look prettier.
The cast is exquisite in their acting and Ji Sung and Park Jin Young create the most sizzling bromance chemistry ever. This is a not a story about a dystopian society but realism ripped from today's headline. There's just not enough words to describe how perfect this is as far as storytelling and acting. Standing ovation to all the cast and crew!
