Best I've watched

Mc Nepwha dies in a mysterious plane crash, and he tries to uncover the truth, by traveling to that country, the story most of the time does not take place in Korea, it takes place in a country In the Middle East (I forgot where), this show is massively action-packed, but unfortunately there is no season 2

It's about catching a psychopath killer, the story is amazing with a lot of plot twist

This show is about 2 detectives trying to solve a murder case, that reappeared 20 years later, this isn't your normal police serial killer case, it is well written, with great acting, and it also has an amazing plot twist

It's About a woman who has superhuman hearing working in a call center, trying to solve crime in under 10 minutes, there are 2 MC the woman and the man, Season 3 is amazing, it's not like the other season, There was 1 reason I gave it a 9.5 which will be revealed at the final ep

It is about a boy whose mother was killed, but the murder got released (it's something about the justice system being bad in Korea), so the MC is trying to make the world a better place by killing criminal

It's a Taxi company who takes revenge for victims

MC is a police officer, who is trying to take down a nationwide criminal organization, but miserably fails, his wife gets killed, and both of his eyes are cut out, NIS approaches him to help them take down the organization and gets 2 artificial eyes to help him take them down

MC was adopted into the mafia, and then went to Korea due to mafia factions, it's a fun-action comedy drama
