This is what happens in this "A killer paradox". It starts of well from episode 1 but when the 1st is going to end you will see some unnecessary transitions something weird one too(actually it is not necessary but i think it was hero hallucinations are shown) how does he feel after murdering someone and how he got superpowers when he sees someone(means serial killers like series called "He is psychometric" ) the feel will come for us then he got to know that he killed a man who used to be serial killer so now he joins hands with the specs guy and they accomplish the justice for victims . I love the concept of it, it was from webtoon so, i did not study it but i feel like it is too slow pace which will make either sleep or you will feel like fast forwarding the scenes itself. There is no AAH moment in this series, so don't except much from this! Again one more serial killer unlike hero will be introduced, and he also started searching hero and finish him off. After few episodes you will be wondering what is happening in this series? And i love every actors performance even the police guy with beard did his job well but he was fore shaded by the plot. At the end of the day, our hero saw 'how to get away with murder" and committed his crimes without evidence, he is the most luckiest serial killer in the whole world.
