It started with a lousy introduction and a decent premise that was simple on paper and then began to jump between one plot after another until the end. There was a desperate need for a better coherent structure and pacing. The plot got overly convoluted for no practical reason. Up until the end, it kept introducing more and more new characters to widen the connection and keep the story running in circles. The characters were more or less fine but a lot of them came off in the form of a generic gangster in a Korean thriller. I appreciate not shoving romance between the leads, it would've been out of place for sure. I liked what they've done regarding the resolution of the bad guys, it had all the ingredients to end horribly but it didn't.
