At first, I started watching this for just some time. I guess it was worth my time. This drama had a different storyline from other cliche dramas. It started off with a good storyline. As a sci-fi drama, I can say it was good, but it could be much better. I didn't like the ending. There wasn't that much romance, but they added it still a bit. I liked the ML there. I saw him for the first time here in this drama; his acting was good. Park Shin Hye acted good too. loved to see her in a quircky character other than an obedient, crying poor girl. I enjoyed every story though; those cases were amusing to watch. If you love thrillers and sci-fi, you guys can give it a go.
