This drama is very touching and has historical values. I actually cried watching this drama. Towards the end, the story plot gets interesting and have me watching it non-stop. Very addictive! Haha...Lee Kang To character which was played by Joo Won is very sincere and his life changed after losing his mother & brother. I do believed that it happens in real life too. After donning the mask, Lee Kang To actually did got injured quite bad a few times. That makes my heart ache and it shows that this drama is realistic. Always will be my hero "Gaksital".
