this is one of the best dramas song joong ki ever did. this is a ongoing kdrama and i couldn't wait to write a review until the drama ends, trust me it's that good. the main character's chemistry is in another level, their dark humor and everything in this drama is so perfect. just every episode in this drama is so perfect and each episode gives such a thrilling vibe to it and its just unique in their own way. the first episode is everything its the one that hooked me in to this episode for the 1 to 4 episodes are the best. its such a cool and thrilled drama, just knowing that they are fighting for justice is just everything. i am a big fan of song joong ki and this drama just made me to even love him more. it's killing me to wait until Saturday to watch a new episode. i highly recommend this drama:))))
