Set in Incheon, South Korea, detectives try to catch criminals, who hide ugly truths. Kang Do Chang has worked as a detective for the past 18 years. He was born and raised in Incheon. He investigates cases using his experience and personal connections, forgoing scientific technique or reasoning power. Oh Ji Hyuk is an elite detective. He has 9 years of experience. Unlike Kang Do Chang, he investigates cases using evidence and insight into the criminal's psyche. Due to trauma from his childhood, he does not share his feelings. He is wealthy thanks to his late uncle, who left him with a large inheritance. Jin Seo Kyung works as a newspaper reporter. She is a 5 year veteran and passionate about her work.

Solid Mystery that falls apart due to unexplicable reactions of female lead reporter
18 November 2020 | by ComphunkSee all my reviews

Everything is wonderful whodunit drama. There's great character development, the plot is Engaging. It's true korean style corrupt police prosecution story, quite similar in tone to Forest of Secrets. But the female lead just blows apart any logical human affection and rationale. How can she have split mind 99% of times as a reporter. You need to watch it to see how her character goes down to depths of complete humiliation of human behavior. Having emotions for killers is something unexplicable. Especially cold blooded murder and an innocent being executed If her character was kept more believable, I would have given it a 9. There's tonnes of comedy. But for me the female lead wrecks it apart by her completely unbelievable affection for the revealed killer
