It is one of the best dramas to have happened to the Korean drama industry. Too strong, too realistic, too tragic. It's not a series that anyone can handle but it is one of the most beautiful series that those who love this kind of series should definitely not miss. The series is actually such a heavy series in terms of its subject that I watched it over 4 days but I enjoyed every minute of it. I cried, I laughed, I was sad, I was happy. It's like every single one of them is a living character for me. I feel so sad and happy that I was able to discover this series. I am sad because the weight of this drama will always be somewhere in my heart. Many thanks to the animation screenwriter who adapted this series and to everyone who contributed to this series.

P.S.: All soundtracks of at the end of the episodes are masterpieces.
