My Demon, one of Netflix’s new K-drama series, features a strong cast of characters led by a compelling protagonist duo. While there have been a lot of Grim Reapers in K-dramas, My Demon takes that trope in an unexpected direction with the story of Gu-won, a demon who feeds off people’s souls. My Demon includes classic enemies-to-lovers and fake marriage dynamics, with Gu-won and Do-hee at the center of an unusual love story.
Like many of Netflix’s best Korean dramas, My Demon will have 16 episodes in total. The series combines comedy, romance, and action in a story that deals with a lot of fantastical elements. However, the show also features family drama and betrayals, namely through the battle for power within the Mirai Group and Cheon-sook’s family.
