it's a perfect kdrama

It is very beautiful, it has a good plot, and its actors are very good. Some people didn't like the ending, but I think it's okay in my opinion. It is a bittersweet drama, but it is very well prepared, all the characters knew how to develop well just like the story. I don't know how to give reviews, but I try to make sure people understand very well. I feel that explaining this drama is a bit complicated, since each person may have felt it differently, but what everyone We agree it is the end. :
