okay first if all the hell ? the drama started off Soo damn good it was literally..I was like why did I not start this earlier ..zi o was like really cool and the female lead too everything was Soo damn good and I was thinking this is going to be my favorite how did no one discover it yet ? ..and yeah the last three episodes definitely proved me wrong ..all the characters went mad ..soon after he had a child he went to the same people who had once tortured him. ..he knew the pain of electric shock and all and still decided to give his child to them ? did he accidentally loose his mind ? I was totally shocked ..his father ? a known maniac. I am Soo sorry but the writer couldn't portray his personality at all ..what was he ? he was a psycho but at the end he was shown as a good person ?..I really felt bad for Yoon na ..she didn't deserve to die at all and the one yoo na loved ? ..he was also mad ..he killed and killed people and didn't run when he had the chance and then went crazy when yoo na died ? ..hello mister ? ..only sane person in the entire show was gu reum and yeah I absolutely hated zi o character ...towards the end he actually became a monster ..he lost his mind ...oh the potential this drama had if only towards the end zio and gu reum would have had a happy ending ..and why exactly did the writer kill gu reum ? ..her death was absolutely unnecessary...she died was telling zi o to destroy his clones and he still did not ? ..what impact did her death had on the entire story ?none ..I didn't even feel bad for her death ..I just felt mad
