This had a lot of suspenseful moments that kept me on the edge of my seat. I didn't know where the plot was going or how things were going to end up. It had a nice dose of comedy injected into the script here and there to lighten things up, but maintained a serious and dark tone throughout.
I liked the human aspect of this plot the most—the confused feelings of the kidnappers at times, and especially the betrayed feelings of the friend that was kidnapped. Once again, it is all for money. Greed and envy gets the best of us sometimes. It really begs the question; who are your real friends?

Casting was ON POINT. It's really nice to see the skills of the actors here. I'd have to say that Kim Dong Hwi gave an outstanding performance. It's not easy playing the villain. He managed to pull it off quite well. Yoo Soo Bin really surprised me, too! At first when I saw him I wasn't sure if they had made a good choice in casting him for the role, but he really blew my expectations out of the water and gave a great performance.

FINAL THOUGHTS... this is a sad, dark tale about betrayal of what was supposed to be a beautiful friendship. It is heartbreaking to see what people will do for money, especially when you consider that this goes on every day in the real world. It is short enough to not have any boring or dragged-out parts, which is a huge plus for me. It would have gotten a higher mark if they had been just a tad bit more creative with the ending. I really liked what they did with Park Min Woo's ending, but for the other characters it fell a little bit flat. Give this a watch! It's only 8 episodes so you can't go wrong.
