My first thought when reading the plot line, was, "A girl who gained the ability of seeing ghosts after an accident? could this be anymore predictably boring?" However, the story actually turned out to be great. Very well written. Very well thought of. I loved the fact that the main characters were different and new, greedy guy and gloomy girl? it just seems weird. but it becomes really impressive after watching the drama. I am very weirdly in love with the male lead character. I think he was the drama's heart. I wouldn't want to change anything about him. The female lead though, confused the hell out of me, at first I understood her, but the she was just, I don't know, she wasn't very developed. I didn't seem to warm up to her. Which is why I think i'm giving this drama less than it deserves. And there is another reason, but saying it would be a spoiler. Anyway, the acting was great. I was convinced. So Ji Sub was, as always, awesome. He completely resembled his character. Face expressions, hand moves, the way he speaks, his reactions, everything was just brilliantly acted. Everything. The supporting roles did a decent job. The chemistry was over flowing. great, great, great, chemistry. The music deserves a 10. More, even. It was fantastic. I kept waiting for the meaningful scenes just because I wanted the music to play. This drama basically has everything. I recommend this to anyone. It doesn't happen everyday to see a drama with horror, comedy, drama, romance, and it even has a plot twist.
