at first I thought it would be very bored, and I could only watch up to 2-3 episodes(my limit to decide to watch drama, 3 episode for 1 hour drama, 3-7 episode for 45 minute drama, if the drama still does not show the opening of the problem, it will be very boring) just to decide whether to continue or not, but the story was more interesting than I had imagined, and each episode was more curious and more interesting, puzzle until the end of the episode,not to much detail not explained almost perfect, nice drama, the story is different and interesting
