I started watching the series while its on going and i have to say its really hard! Waiting every week for an episode then something suspenseful happened but you have to wait a week to know what really happened. The stoy was indeed very unique I haven’t seen any story or drama like Flower of Evil. The actors and actress’ chemistry was great too! I mean well Lee JoonGi never disappoints! I also love the OST especially DOKO’s Psycho!! The song is really great it matches the show’s theme. The reason my rewatch value is low because i think knowing the story is okay already don’t feel like you can keep on watching it again and again.
