Solid kdrama. The supernatural/power parts of the kdrama were built up and explained well in the end, and it made sense in the context of the culture. I liked the characters except Seo Ha, the guy has like 2 emotions and is also the worst decision maker. Why they would make him director of a hotel is beyond reason besides being a nepo baby. I wish they would have explored the other lives more in depth. I cannot believe they shot obscure no context scenes of her life in WWII Korea, full with likeable characters and absolutely stunning settings, only to see like 3 or 4 second snippets during her flashback. Why was he playing the guitar? What was the story? Exploring the stories of the different lives would have added so much flavor to the story.
