All the actors was awesome. Rain, Daniel, Lee Jung Jin and other detectives. There is a big BUT in here. You know when you watch a drama you usually expect the lead actor & actress to have chemistry between them but there is none! I don't know if this is because of Rain's character Ji Woo is funny and playful, make you enjoy the drama and others not! Still her acting is not good as the others. Her eyes were blank all the time. She don't use gestures when she acts. There was some good points but if I say them that would be spoilers :) Soundtracks are awesome. You wanna listen Oran-G - Mayday and MBLAQ songs that used in this drama, again. I'm a fan of Rain since I watched Ninja Assasin if you didn't watch it, you should. Lee Jung Jin is a good actor and his smile makes you smile, maybe generally you can't call him handsome but he is attractive. When you start this drama, you wanna see his scenes more! Storyline is intersting. It starts from past and makes you curious. But there were so many characters. And this drama should be 16 episodes. They just dragged on meaninglessly. But still you don't regret it after watching it.
