It was sweet, simple and satisfactory. Nothing to write home about honestly, Kim Bum was precious and pure perfection as he is in everything, the villains were basic and nonintimidating, I didn't care about the main romance at all and the side romance was just a few lines from being nonexistent. The story line undoubtedly could've been summed up in 12 episodes, the backstories were straightforward, with very little plot twists and the side characters were fine. Also the main ghosty guy was cool but I honestly have no idea why he had to stick around for like 15 years. I wish Rain and Bum had better chemistry but I just didn't feel it as strongly as I wanted to. The ending wrapped up with little to no conflict and complete resolution. It was a lighthearted, easy ride. Kind of like a GAC movie, nothing over the top or super deep.
