A 200-year-old demon, played by Song Kang, finds himself drawn to a human, Kim Yoo Jung’s character, despite having despised humans for centuries. His past haunts him, yet he goes to great lengths to protect the woman he loves, sacrificing himself in the process.
On the other hand, Do Do Hee, an heiress who lost her parents at a young age, finds comfort in Ju Cheon Suk, her late parents’ close friend, portrayed by Kim Hae Sook. Their fateful meeting causes Jung Gu Won to lose all his powers to Do Do Hee, binding their lives in ways neither of them anticipated.

My Demon’s Grand Finale
The supernatural K-drama starring Song Kang and Kim Yoo Jung reached its conclusion on Saturday, January 20. Episode 15 delivered an emotional moment as Jung Gu Won gave up his life to save Do Do Hee, who had been killed by Noah Sok Min.
Meanwhile, the antagonist was sentenced to a lifetime behind bars. Left heartbroken, Do Do Hee was inconsolable as she grieved the loss of her beloved. However, the final episode introduces an unexpected twist—Jung Gu Won’s superior, whom he refers to as god, grants him a second chance at life.
This was the outcome of a bargain Jung Gu Won had made earlier, allowing him to reunite with Do Do Hee and their cherished friends.
Did Song Kang and Kim Yoo Jung Get Their Happy Ending?
The burning question remains—was there a happy ending? The answer is a definite yes, and it happened in an instant. The leading couple cleared up all lingering misunderstandings and chose to continue their journey together, embracing everlasting love.
At the same time, Park Bok Gyu and Shin Da Jeong also found their happiness.
The Truth Behind Do Do Hee’s Parents’ Fate
Jung Gu Won finally discloses what truly happened to Do Do Hee’s parents. They had been involved in an accident while her mother was still carrying her. Because he could not grant a wish to save all three of them, a deal was struck with her father, who made the painful decision to prioritize Do Do Hee’s life over their own.
As part of the agreement, both parents would pass away exactly ten years later. This means they had been aware of their fate long before it happened.
Who Took Over as Chairperson of the Mirae Group?
With the unanimous support of those involved, the responsibility of leading the Mirae Group fell into the hands of Ju Seok Hun, played by Lee Sang Yi, the most suitable person for the role.
Jin Ga Young’s Journey
One of the most touching moments in My Demon’s conclusion was when Ga Young rescued a child from domestic abuse, mirroring the way Gu Won had once saved her.

Changing the entire conversation and reassuring the child that there would always be someone ready to protect them made for a truly emotional and uplifting moment.
Kim Sa Ra’s Lesson
Jo Yeon Hee’s character, Kim Sa Ra, who was married to Noah Sok Min, had a change of heart towards the end of the series. In the final episode, she approached Do Do Hee to express her determination to establish a shelter for children affected by domestic violence, deeply moved by what happened to her child.
A Look at My Demon’s Performance
The drama kicked off with high expectations but gradually experienced a decline in local ratings, settling between 4.6 and 5 percent after debuting at 9 percent. However, this did not stop it from becoming an international success on Netflix.
Despite facing hurdles in the domestic K-drama scene, Song Kang’s charm kept the series at the forefront, making it the most talked-about show while earning him the title of the most talked-about actor week after week. For anyone in search of a series that offers an engaging escape, My Demon is certainly worth watching.
