There are things in this drama that could have been different but I still give it a 10. It is a drama that really touched my heart and I could relate to the main character, it is a beautiful drama.
To be honest the first episode bored me but I'm glad I gave it a second chance, the plot is simple but I couldn't stop watching it.
The last episodes were very sad but I liked how the characters dealt with it. I'm really going to miss this drama. In the future I am sure that I will see it again, now it has a deep meaning for me.
Obviously there were things that I didn't like like, for example, that Gu didn't overcome his alcoholism problem, I would really have liked his character to change like the others.

I really have to say its not a drama for everyone.
