Just finished watching the series. The series is of 8 episodes and is not like most of the kdramas, the directography, the plot, the videography, the bg music is different from most of the kdramas. This is a psychic thriller show with a distinctive storyline.
The characters are also unique , not too many cast involved, but it defintely starts getting creepy. Overall a good show to binge watch, the actors did a good job, specially Young Kwang, playing a role of an absolute psycho. It might be a bit slow, but I think that was the also the part of context of the series, to get slow and creepy.
