Plot: Fantastic plot that always leave you wanting for more. The characters, the storyline, the relationships and chemistry everyone has with each other really hits hard on the feels. Found myself crying, laughing, awing so many times. Perfect from beginning middle and end. Cast: freaking loved lee jong suk and lee Bo young. This is the couple of the year for me. Really likeable cast, and hateful villains. Acting was perfection. Character development for all the cast members were great. Music: great ost, but I couldn't remember any significant songs I really loved. Overall: this is definately the drama of the year for me, and one of my favourite dramas of all time. It incorporates everything, sweet romantic scenes, revenge and vengeance, action, betrayal, trust and loyalty, and teaches one how to forgive and make amends.
