After reading the comments, I think everyone will hate me for this: I actually liked the drama. It’s not the best, but it’s been a while since I’ve been looking forward to one episode after the next. I learned to enjoy the process despite their time-traveling storyline. However, I recommend that anyone who has not completed it either not watch the last episode or don’t expect to find any solutions. As @nanika said, I felt baited too. It’s as if someone didn’t broadcast the other half of ep20. No closure whatsoever. I commented somewhere on YT midway, hoping that this drama wouldn’t flop in the end. I guess I jinxed myself. -_-
