KajoPicks: 10 serial killers from Korean dramas who terrify us

There is one thing you should know about serial killers in Korean dramas; they do not usually appear in thrillers or crime dramas.

Sometimes, they appear in romance or even comedy dramas.

Regardless of which genre they appear in, some of these serial killers from Korean dramas are terrifying to watch.

Here are 10 serial killers from Korean dramas who terrify us:

1. The Painter Killer in Born Again (2020)

The main theme of this drama is reincarnation; about three people who remain entangled in a love triangle and murder even after being reincarnated.

In the 1980s, Gong Ji-chul (Jang Ki-young) was a lone wolf living under a controlling father.

Meanwhile, Jung Ha-eun (Jin Se-yeon) and Cha Hyung-bin (Lee Soo-hyuk) are a couple very much in love with each other.

Ha-eun is the owner of a secondhand bookstore called ‘Old Future’ and Hyung-bin works as a detective.

While chasing the true perpetrator behind a string of murders, the three of them get caught in between the cases and eventually died.

30 years later, the three of them are reincarnated. Gong Ji-chul becomes Cheon Jong-bum, a medical student. Hae-eun is reborn as an archaeologist named Jung Sa-bin while Hyung-bin is a prosecutor named Kim Soo-hyuk.

What happens when the string of murders that took place in the 80s repeat themselves? Did the original killer die, get reincarnated and start murdering again? Was the real killer never caught in the first place? Or did the murderer find a protege to carry on the murderous torch?

As for the terrifying serial killer in this drama, the culprit kills in the name of ‘art’. He paints his victims after laying them down in their graves the way he wants.

While this serial killer is terrifying, what is more disgusting are his cult followers who love his ‘works’. They even have secret chat group to talk about their ‘fandom’.

This reminds of us serial killers such as Ted Bundy, Jeffery Dahmer and Aileen Wuornos who have secret online groups for fans on social media platforms such as Facebook.

2. The Genius Killer in Gap-dong (2014)

Speaking of real-life serial killers, here is a drama inspired by one.

Set in 1986 in fictional Iltan city, a young girl is found brutally murdered. Since then, a series of murders has been found committed in the area.

The police nicknamed the suspect “Gap-dong”. The authorities also mistakenly identify the killer, causing the wrong suspect to commit suicide to prove his innocence. His death inspires his son Moo-yeom to become a police officer to clear his father’s name.

Seventeen years later, a new victim shows up sharing a similar pattern with the victims of Gap-dong. Are they the works of Gap-dong or a copycat killer?

These cases were evoked by the Hwaseong serial murders, a series of rapes and murders that occurred in the rural city of Hwaseong in Geonggi Province between Sept 15, 1986 and Apr 3, 1991.

The victims – all women – were found bound, gagged raped, and strangled to death with their own clothes.

The cases remained unsolved for 30 years until Lee Choon-jae was identified as the suspect in 2019.

In an interview, Jae-wook revealed “After shooting the gory scenes in which I had to torture and murder a person, I had breathing problems and I couldn’t stop shaking.” He also couldn’t bear to look himself in the mirror after shooting this drama.

This police procedural series centers around Kang Kwon-jo (Lee Ha-na) who works at an emergency 112 call center. Together with police detective Moo Jin-Hyuk (Jang Hyuk), the duo try to catch Tae-goo.
