I rarely write reviews but I enjoyed this enough to recommend it. The characters were so well written and all served the story well. Loved watching the relationship between the granddad and grandson which was complex but somewhat endearing. I'd say better than the romance plot which was appropriately sprinkled in and there was good tension and chemistry there. I enjoyed the plot twist at the end and that no supernatural entities were introduced here to explain how it happened. I rarely care for kdrama endings but I was fully satisfied with how things concluded that I wasn't angry and wanting there to be more or know more or want to follow up further. It was just right.
