I watched this because of Min Seok but I love how I fell inlove with the other two too because of this movie. This movie is about how knowing martial art is important and where it can be helpful but it's not directly telling you that everything needs to be solve through brutality and trouble instead, it teaches you that it is important to know martial arts because you can use it when you're in an inevitable situation but if you can avoid using violence to solve something, it is better to proceed in that way. I think it is a realistic situation, like how we, humans, can be carried away with different situation and on how we face its consequences (Just like how Woo Sol chose to be imprisoned).
