If you looked at the poster, it may look like many other kdrama but believe me, it's NOT. A totally different experience, good senses of humor, exceptionally scenes and on top of that, every character did very well in their role. You will laugh, cry and get too much emotional.
Don't hesitate, just watch and you will never regret it. Well maybe one, your standard is now so high that it's difficult for you to enjoy other series.
