Don't mistake the slow pace of the series as boring since the writer and director duo intentionally slow the series down to focus on the raw emotion and interaction between the characters. In that sense, this kind of series might to be everyone's cup of tea.
The series presents the story in a very organic and natural manner, without too many lazy writing (as in forcing stuff happens that conveniently benefit the story in the name of fate). The acting of the main cast is good.
However, there is one big blunt that might annoy you quite a bit. Somehow, all the romantic scene is accompanied by 1,2 songs. The repetition is quite annoying after a few first time and greatly diminishes the wathching experience
