This drama was awesome, don't listen to the overly negative reviews and ratings. The production value and cinematography were simply gorgeous... Every scene seemed like a painting from some cold, brutal, corporate dystopia; I also liked how the lighting changed in the past vs current scenes. The acting was uniformly great and the story did what it could in such a short runtime. I just wish this drama had more and longer episodes.
Even though it's not on the same level, this drama really reminds me of Someday or One Day and I'm really enjoying myself. The OST is also awesome. I just hope the acting improves; the plot is really interesting though.
Wait do you understand Japanese?
