The best and most important thing about Japanese drama is that it intensify events and feelings in a short period of time. In this drama , they showed a lot of feelings and showed that logical thinking, conclusion, and analysis are necessary, but not more important than relying on intuition. One of the thoughts that he focused on is family and its importance, and that brotherhood is the most important , It doesn't matter if we disagree or be different in thoughts or principles, but it doesn't lead to hatred or destruction. I also like the Japanese drama switching between events and people, what you expect the solution becomes the problem and what you expect the villain becomes peaceful and good.
