Wow what an exciting drama. The storyline is beyond my imagination it gets better and better the more I watch. Everyone has there own opinion about this drama. I think the cast is doing a phenomenal job portraying there characters. The story started as a person is being chased with a baby and dropped it " saying your not a monster. The ML and FL are building up there chemistry, she always thinks negative of him even after he saves her life a few times. All he wants to know is who his is and get his memories back, I don't think he's dangerous. I feel he's scared and alone and everyone is trying to catch, fight or kill him and in order to protect himself or someone he likes he looses control and electrified everything around him. He didn't ask to be made this way and used as a lab baby and injected with all kinds of concocted animal dna. While keeping a low profile the FL is hit by car and he preform cpr/defibrillator as people are video taking and makes the news. I know the FL is looking for her parent's and needs his memories to return in order to give her some clues if there dead or alive. They only show a scene of her mom and her dad leaving with the ML and never returning. Her dad worked in the research lab and had most connections to the ML not sure
for a new life in exchange for the ML. He hands over the ML and is told once they confirm his blood the money will be transferred as they take blood and a skin biopsy the ML screams in agony and blows up van after that we don't see what happens. During a flash back of Kim cheol soo you see him chasing ha young ji the FL dad asking for the kid and all the lab data and that's it. So now we're at the point of the ML wanting to take control of his life and not involved anyone so goes to Human Tech to confront them and is captured and tortured by his father while they extract blood, tissue and use electricity to see how far he can go before dying then they use defibrillator to bring him back as his body can rejuvenate from injury. I guess he dad felt guilty and didn't kill him told him to live and find his answer. As he trys to break loose he's destroying everything in the lab, on the other FL is looking for him and a fight Break she finds appx6-8 babies and put them on elevator as she goes to help him, she hit in the head he saves her and the babies. Takes her to hosp. She has a fracture in head she is treated when he hears they accused her of 11 murders she takes her to jin soo home while they figure out next step and jin soo remind him of the county where they worked. She call her boss who track the number and goes after her, again there on the run to the country side.. they hide out for 3mo. happliy until she accused of murder again and she thinking to go back in a few days instead while upset they sleep together and she agree to stay a few more days which turns to a month or 2 and finds out she pregnant. Everything was going good they have a baby girl so far normal, but fake news that her parents found dead and caused by electricity so she calls her partner and the chief over hears snd send the bad guys and they kidnapped her/baby. Now the ML is mad and start trouble looking for them in the meanwhile she starts to believes the chief that ML killed her parents.
This is where she starts to becames dumb and chooses to believe the people who have manipulated the news over her husband. Now again she is kidnapped by the cult leader and dr.ryu joong kwon(his parents) who show her how he was made by an experiment and not human and that he killed her parents and she should stay there. He finally finds her after his best friend is killed by Lee son since ML killed yuna. Once at church she does not want to see him since she believes his parents he stills denies and explained that the cult manipulated the news. He try to keep her there since it was safe, but the bad people find them and have order to kill all but the baby and him. He helps her get out and she runs into her chief and still thinks he bad until he take a knife for her and he explained that ML didnt kill her parents and helps her get away. She meet old partners and ask him to watch baby so she can get the guy Ken who killed her parents. She beat him up and took him hostage and meets old partners to switch baby/killer when the cult charges and start killing everyone for the baby. The ML is trying to get there to save FL/baby and now were back to the beginnings of this drama. She takes a bullet for him and says take the baby away. TBC? Part2
