## Premise and characters
The story centers on two people who are each used to getting their way. Do Do-hee (김유정 as the actress, 도도희 as the character), the adopted daughter of the powerful businesswoman Joo Cheon-sook, is the CEO of Mirae F&B, a subsidiary of the Mirae Group, and has many enemies.[6](https://www.nme.com/reviews/tv-reviews/my-demon-review-k-drama-song-kang-kim-yoo-jung-3555104) • [10](https://www.forbes.com/sites/joanmacdonald/2023/11/26/a-marriage-contract-might-redeem-a-soul-in-the-k-drama-my-demon/) Jung Gu-won (정구원), played by [Song Kang](https://www.edgepedia.org/song-kang), is a 200-year-old demon who makes contracts with desperate humans, collecting their souls in exchange for help, and who does not think much of humans.[6](https://www.nme.com/reviews/tv-reviews/my-demon-review-k-drama-song-kang-kim-yoo-jung-3555104) • [10](https://www.forbes.com/sites/joanmacdonald/2023/11/26/a-marriage-contract-might-redeem-a-soul-in-the-k-drama-my-demon/)
The turning point comes after an ill-fated blind date arranged by Do-hee's adoptive mother: a night attack on a misty road leaves Do-hee calling for help, and Gu-won answers, but the encounter binds the two together when his tattoo, the source of his power, transfers to Do-hee.[10](https://www.forbes.com/sites/joanmacdonald/2023/11/26/a-marriage-contract-might-redeem-a-soul-in-the-k-drama-my-demon/) • [6](https://www.nme.com/reviews/tv-reviews/my-demon-review-k-drama-song-kang-kim-yoo-jung-3555104) Gu-won loses his supernatural abilities when his powers and the cross tattoo on his wrist are transferred to Do-hee, so although he looks down on humans, he must enter a contract marriage with her to protect his own existence.[10](https://www.forbes.com/sites/joanmacdonald/2023/11/26/a-marriage-contract-might-redeem-a-soul-in-the-k-drama-my-demon/) • [15](https://www.soompi.com/article/1628431wpp/song-kang-and-kim) The marriage contract stipulates that the two will outwardly present a perfect couple, with romance expected to follow the wedding rather than precede it.[8](https://ent.sbs.co.kr/news/article.do?article_id=E10010281154)
## Plot progression
**Contract marriage.** In episode 6, broadcast December 9, 2023, Do-hee accepts Gu-won's proposal after a near-fatal attack, and the two marry in a ceremony staged for the Mirae family. The episode recorded an average rating of 5.1% and a peak of 6.7% in the capital area, with a 2049-target rating of 1.8%.[8](https://ent.sbs.co.kr/news/article.do?article_id=E10010281154) Later episodes move into newlywed cohabitation, Gu-won's fluctuating powers, and the couple's investigation into attacks on Do-hee and the death of her adoptive mother, with suspicion falling on the Noh family.[4](https://www.rottentomatoes.com/tv/my_demon/s01) A dream sequence reveals a tragic connection between Gu-won's past life and Do-hee, and the finale, "Our Personal Heaven," aired January 20, 2024, centers on Do-hee's Christmas wish for Gu-won's return.[4](https://www.rottentomatoes.com/tv/my_demon/s01)
**Supporting cast.** Lee Sang-yi plays Joo Seok-hoon, Do-hee's adoptive cousin and a loyal friend who complicates the central relationship without becoming a simple rival.[5](https://www.justwatch.com/us/tv-show/my-demon) • [11](https://celluloidscore.com/reviews/my-demon-review/) Kim Hae-sook plays Do-hee's adoptive mother, the head of Do-hee's corporate family.[10](https://www.forbes.com/sites/joanmacdonald/2023/11/26/a-marriage-contract-might-redeem-a-soul-in-the-k-drama-my-demon/) • [11](https://celluloidscore.com/reviews/my-demon-review/) Other cast members include [Lee Yoon-ji](https://www.edgepedia.org/lee-yoon-ji) as Noh Su-ahn and Kim Tae-hun as Noh Suk-min.[5](https://www.justwatch.com/us/tv-show/my-demon)
## Reception
Critics split sharply. [Kim Yoo-jung](https://www.edgepedia.org/kim-yoo-jung)'s performance drew consistent praise; the Film Companion review singled out her portrayal of an exceptionally intelligent woman aware of how alone she is, and the review site Celluloid Score gave the series 4/5, calling it a slick, charming fantasy romance carried by the leads' chemistry.[4](https://www.rottentomatoes.com/tv/my_demon/s01) • [11](https://celluloidscore.com/reviews/my-demon-review/) At the other end, the [South China Morning Post](https://www.edgepedia.org/south-china-morning-post)'s review of the finale awarded 1/5 stars, describing the series as trite tropes and endless product placement that ended in the most unsatisfactory way possible.[9](https://www.scmp.com/lifestyle/k-pop/k-drama/article/3249279/netflix-k-drama-review-my-demon-kim-yoo-jung-and-song-kang-cant-save-manufactured-and-lazily?module=inline&pgtype=article) Reviews on Rotten Tomatoes average to a 60% Tomatometer against an 80% audience Popcornmeter, a gap that matches the split between professional and viewer responses.[4](https://www.rottentomatoes.com/tv/my_demon/s01)
**Ratings trajectory.** The series premiered at 4.5%, dipped to a range of 3.4% to 4.2%, and rose to 4.7% at episode 6, while the same-slot MBC drama *[The Story of Park's Marriage Contract](https://www.edgepedia.org/the-story-of-parks-marriage-contract)* nearly doubled from a 5.6% premiere to 9.6% over the same weeks.[12](https://koalasplayground.com/2023/12/09/weekend-dramas-my-demon-and-the-story-of-parks-marriage-contract-delivering-solid-entertainment-of-the-fated-and-supernatural-romance-but-ratings-starting-to-pull-apart/) The 6.7% peak for episode 6 was the series' highest instantaneous rating reported in the period covered by these figures.[8](https://ent.sbs.co.kr/news/article.do?article_id=E10010281154) • [12](https://koalasplayground.com/2023/12/09/weekend-dramas-my-demon-and-the-story-of-parks-marriage-contract-delivering-solid-entertainment-of-the-fated-and-supernatural-romance-but-ratings-starting-to-pull-apart/)
## Place in the genre
The series belongs to the contract-marriage and supernatural-romance line of Korean dramas, and reviewers repeatedly placed it alongside *Goblin* (2016) and *Doom at Your Service* (2021), which share the premise of a powerful supernatural being bound to a human.[13](https://korean-binge.com/2024/01/21/k-drama-review-my-demon-2023-24/) • [14](https://www.dramaasianreviews.com/post/my-demon-a-delightful-blend-with-room-for-improvement) Some critics treated these similarities as derivative, while others described *My Demon* as a fresh take built on a new immortal character and the pairing of Song Kang and Kim Yoo-jung.[13](https://korean-binge.com/2024/01/21/k-drama-review-my-demon-2023-24/) Its reviewers also noted that the supernatural rules, including a demon who perishes or fades through spontaneous combustion upon breaking the rules, resemble devices used in earlier fantasy dramas.[13](https://korean-binge.com/2024/01/21/k-drama-review-my-demon-2023-24/)
