The lock down of 2020 did spur some changes in entertainment viewing habits. Through streaming services like Netflix, international audiences have been exposed to k-dramas. South Korean television shows have their own set of tropes and story lines which are fresh to new audiences. One gateway series was "Crash Landing on You" which had an unbelievable premise (a South Korean heiress has a paragliding accident by crash landing in hostile North Korea only to find love with a NK soldier.)
A smaller network is promoting a new 2021 series.
The OCN Network is casting a new k-drama that may interest LOST fans.
“Island” is a fantasy exorcism drama based on a webtoon of the same name. It will tell the story of man who needs a woman to end his cursed immortal life and a woman who does not know about her sad and cruel fate. The two are joined by an exorcist priest who is consumed by the guilt of having been unable to protect one girl. On the island that possesses an evil darkness despite its beauty, the three characters who seem unlikely to get along will gather their strength to protect each other.
Won Mi-Ho is the only child of a father who runs the Daehan Group. She is arrogant and selfish, but she also looks sad. One day, she makes big trouble. Because of this, her father banishes her to Jeju Island. She is assigned to work there as a high school teacher. She teaches ethics. Meanwhile, Won Mi-Ho gets involved in a case related to ghosts. The ghosts have sought to get rid of the human world. They target Won Mi-Ho. A mysterious ghost hunter tries to protect Won Mi-Ho.
At first glance, the premise seems to be a concentrated version of the original LOST premise. A mysterious island inhabited by supernatural beings where human visitors need to unravel the mysteries in order to save themselves and mankind.
