"A love that transcends law" - The story was written excellently and I found no holes within the plot. Everything made sense and this show did a great job on providing insight upon how both North and South Korea operate and work together when needed. I loved the cast especially the two main leads Se-ri and Jeong-hyeok. Their personalities were polar opposites which resonates with where they are originally from. On screen their partnership and relationship was admirable and they were a perfect pair. I'm happy to know that they are married in real life. Cheol-gang was one of the greatest villains I have ever witnessed as he nailed his role perfectly and he gave off the performance needed to create tension and discomfort within the viewers. The secondary couple Seung-jun and Seo Dan were charismatic leads in their own regards, I enjoyed their relationship and and I found them to be key pieces pertaining to the story. Jeong-hyeok's comrades carried the comedic segments of the drama. Chi-Su, Eun-dong, Ju-meok, and Gwang-beom were amazing together and were very entertaining. All four of them had nothing in common except their pride to defend North Korea and their loyalty to Captain Ri Jeong-Hyeok, which was admirable. The OST was great and the drama contained many songs to fit different themes. Overall, this drama was most definitely a classic, and everyone must watch it!
