I didn't expect to like this drama this much. It has a great cast, VERY unique premise and interesting and complex relationships between the characters. I like how almost all the characters are morally ambiguous - this is an accurate depiction of real life, in which morality isn't black and white, and every hero doesnt wear a cape and isnt perfect. I liked how even the worst characters (Ji-han aside, we all hate him) could develop and become a better person with the help of others. I think the romance left something to be longed for as it mainly focused on the supernatural connection between the two, which is important but i think there couldve been slightly more in terms of textbook romance, however the plot wasnt frustrating and angsty, and that i applaud since watching a romance that turns angsty mid-drama is like living hell on earth. My main qualm with the plot is the gwi-ju dying and then being brought back into present life by his son arc. Although the ending is good, it felt rushed and i often feel frustrations with dramas which spend more time showing the troubles and then once they resolve them, they leave you with five minutes to enjoy them. This drama did just that, only on the penultimate and final episodes, however. I REALLY loved hyeong-tae and grace's characters, they added a light comedy element to the drama whilst also balancing menacing and comforting personas. What i particularly loved was the scene in the penultimate episode, where the three girls essentially collaborate to destroy jihan and put their positions as frenemies aside. I smiled so much when i saw Dong-hee taking grace through the air and the three rejoicing afterwards - it was really heartwarming. I also enjoyed hyeong-taes soft protective gestures, and the way he made sure to keep everyone safe without their knowledge - this was honestly so sweet. I-nas plotline at school was not really of any interest to me and i found it rather boring and generic, but what i did enjoy was her relationship with gwi-ju becoming better, and her finding a mother figure and a friend in da-hae. This drama was a good watch and i would recommend it to others. Shoutout to choi Gwang-rok and ryu abel, i enjoyed their acting the most.
