Wow, awesome cast and fantastic sounding creepy premise! OCN has confirmed for early 2021 the thriller K-drama Dark Hole and signed up as leads Lee Joon Hyuk and Kim Ok Bin. I’m sure there will be zero romance and I’m totally cool with it since these two will bring intensity and the right seriousness for this story. The drama is about people who turn strange and creepy after breathing in the air from a strange cave, if they are lucky enough to survive. Sounds like mangaka Shinohara Chie’s famous twins and creepy cave air supernatural powers 90’s manga Umi no Yami, Tsuki no Kage. Kim Ok Bin plays a detective (of course, OCN drama and all) who goes to the cave after receiving a call from the serial killer who killed her husband while Lee Joon Hyuk is a truck driver who was a former police officer who left the force due to a misunderstanding leading to dishonorable discharge but still maintains a strong sense of justice. They meet and seek to help those who have fallen into this danger. It’s from the PD of movie Cellphone and the screenwriter of Hell is Other People.
