I found this J-drama to be excruciatingly slow-paced, which made it quite dull to watch. From episode 4 onward, the pacing became so sluggish that it felt almost unbearable, to the point of being frustrating. Still, I managed to see it through to the end. The storytelling leaves much to be desired, as it unfolds in a somewhat circular manner, relying heavily on flashbacks. Unfortunately, the main characters are largely unlikable, which only added to the overall disappointment.
(good point: good looking cast)
