This was just fucking amazing through and through. I initially watched this because it won Best Drama in Baeksang, and it has Jung Hae In in it so I was intrigued and what I got was a poignant yet dark grim sad story showcasing the broken military system in South Korea. I can't even count the amount of frustration and anger when I was watching the abuse and mistreatment especially to Suk Bong. It perfectly showed how the Military System is broken and such, and the story was well portrayed without being too complicated and muddled. Thankfully, the show also has slight comedic and light moment because of Han Ho Yeol played fantastically by Koo Kyo Hwan. Jung Hae In was fucking amazing especially in Episode 6 the scream was so painful but the star of the show is Jo Hyun Chul as Cho Suk Bong, he gave it all in this performance. It was so heartbreaking to see probably the most kindest character in the whole show slowly descent into madness after being mistreated several times. The ending was good, it gave us opportunities for the second season and the fucking post credit scene in the last episode was shocking. Overall, a masterful korean drama with a great story, delivering a dark grim message and perfect performances from the ensemble cast. I rarely give 10, but this drama deserves it and I hope the second seasons holds up to it's predecessor.
