In all honesty I was stoked and hyped for this show in the beginning. but by the end of the beginning I started losing interest. I'm hard core into serial killers so whenever that part was mentioned I was all for it. However, by the middle there were already a few plot twists and it became repetitive. The theme song was sadly better than the whole plot to me lol Overall I was decently satisfied, but DEFINITELY was left craving more. The ending has me feeling some type of way so that's why my re-watch value is minimal. Toward the end it felt rushed and sloppy making it unfortunately, probably the least favourite of my psychological killer/thriller dramas. Lee Joon aka Ryu is bae and made the show as bearable as it was for me lol
