i will give you my opinion and base on it you will decide if it worth watching or not cause for me 1000% was worth watching and be one of the best k_drama i watched in long time , this drama is detective/action/drama ,
but the power it was the supper supper good writing and execution cause they made so invested in the plan of the main leads i was so into it that i couldn't control my anger when he almost got caught and i was so happy when he reached what he want , it was just so well played that it made a non fan of action/detective genre like me be so impressed and amazed on how it turns out ,
