this drama was out my expectations, every single episode left me hanging,i was dying to know what will the next episodes, it makes all these emotions inside of you explode. I cried way too much because of the realistic scenes and the storyline, i laughed too dont worry. the cast was really good,Kim Wo Bin was the one who made this story so realistic his acting is so good, the chemistry between the two leads was 7/10 but suzy had to work more on her acting skills she was off on some scenes, and the evil characters did their job really well. the soundtrack of this drama will stay with me for a long time i really really loved it applause to who ever chose it. at last, the way the story develops is a bit slow but i liked that,and the story was so unexpected in my opinion. ill definitely re-watch it in the next 8 years, its worth to watch drama you should give it a try !
