Did he disassemble neck chip with his HAND? LOL This series definitely reflects 2050 years , not 2020. The characters were very well drawn (Except for a fighter woman) The attitude of the female fighter was very contrived.The series has become more and more silly. The final was very complicated I think screenwriter was afraid of the audience's reactions if finish did not finish happily. I guess they didn't get bored anymore. it turns out that the good guys we come across are actually bad in every series. And audiences can understand this from the first episode. I think some Korean dramas are in a vicious circle. I can understand how can artificial eyes control human . but it was ridiculous to be able to access confidential files. I was very hurt by the first 3 episodes. Bro got his eyes newly. Leave him a little alone! There were many points in the series that made me nervous but even so I had fun watching it.I recommend watching more realistic series such as Voice and Tunnel.
