This is one of the best shows I've ever seen; not just including Korean dramas, but all shows. The plot was immediately exciting and intense, and the build- up of mysteries was very intriguing. The characters are really well-developed, and the relationship between Baek Hee Sung and Cha Ji Won is one of my favorite drama relationships. The atmosphere of the show was at times heartwarming, while at other times psychologically chilling and eerie- both lighter moments and darker moments were very immersive and well set up. Part of this was the music; DOKO's Psycho is one of my favorite drama ost's. Even just the song has perfectly unsettling lyrics... "I want your breath, I want your hair, I want your fear, please don't ask me why..." Every part of what goes into the show makes it feel so full and impactful.

One of the best parts of this show was uncovering the psyche of Baek Hee Sung aka Do Hyun Soo. If you want to watch a straight-up serial killer, go for a show with a typical cartoon villain. Flower of Evil explores nature vs nurture, humanity, and the good versus evil that exists in all of us. What I loved is that the show introduced Hyun Soo as a secretive villain and potential serial killer- but then the audience sees more and more that he really is a good person, but his differences and issues alienated him, and made him unable to consider himself capable of goodness or love. I consider Hyun Soo one of the best, most complex characters I've ever seen. I also loved his relationship with Ji Won; Ji Won was intelligent enough to uncover his secret, but she ultimately fought to have faith and loyalty to him. All of the acting was stellar; Kim Ji Hoon also deserves recognition. He started off sympathetic and became terrifyingly unhinged.

At first, I was unsure of how to feel when Hyun Soo developed amnesia in the last episode. However, after considering it for a while, I think it's a very good and fitting ending. First of all, it's not like it came out of nowhere; the writers already showed us with Jung Mi Sook that a certain level of trauma will just break your mind, which is why she also had amnesia if I recall. Hyun Soo was already mentally fragile and unhealthy; Ji Won's death would've been devastating to anyone else in his position, but for Hyun Soo, I think it was just too much for him to handle. He wasn't even sure at that point what was real or not. That, combined with the physical trauma, definitely would've left damage. In addition, Hyun Soo had been living as Hee Sung for over a decade. Even though Ji Won knew his identity, years and years of lying and acting wouldn't have just stopped. Baek Hee Sung still would've been a part of him. Now that he has amnesia, he can be his true self, and make decisions by the feelings and love he still has instead of the cover he built up- something that brought his arc full circle. He thought he couldn't love and now love is the only thing guiding him.
