This is the same director that filmed "Signal" and "Incomplete life", so of course, I had to watch it. Ever since he filmed Sunkyunkwan Scandal(in which Song Joong Ki and Yoo Ah In and Park Min Young won their popularity), I had my eyes on him. Any mediocre actor will win popularity through this director and Yim Si Wan is one of the many! This director has a knack for making every story so personal and special yet a different chill will run through your spine every time you watch his works. This film was a little(?), maybe a lot different different than his previous ones and I think he is the type of man who goes for challenges. I loved all of his films but this one in particular, I couldn't watch without crying from episode 6, and you will understand why.
This film was, compared to his previous ones, more deep and you will learn to hope and how to be a proper adult in the midst of hardship in life and what it means to be a real hero. He has a special way to resolve struggle and obstacles and deliver you to perfect climax and resolution. I highly recommend it and I hope the subtitle will be able to deliver the subtle yet strong message, and the beauty of this film.
