One of the best drama. The ending was the next level and i seriously wish season 2 comes soon. The story is really amazing and it is totally worth watching, i loved main roles everyone was amazing. Dont hesitate if you feel they are many characters once you start watching, you will understand each and every character and its very clear and easy watch.. the suspense and the thrill in each episode was breath taking. SONG JOONG KI seriously was amazing in this drama and he is always best with his acting in any drama or movie . And i respect him for his acting. He was the best and hope you release season 2 sooner, even though it takes time
