Overall, the kdrama was really good. The story, the plot was intresting. But, one thing is Song Kang character development too lame. Too drag. His acting feels like empty, too straight. Another, the ending could be even moreeee better. What's that? The parasite just die like that? I wait for nothing. This drama can be just 2 seasons only. I gave 8.0 because this drama have something. Have an aura. I love everything except character development of Song Kang and the ending. Overall, it is a good Kdrama. Bravo. Hwaiting!
