I already watched korean version so story is same but the difference is korean drama is lengthy and this drama is short .It depends on viewer choice which one has to watch . Those live to see more romance and like lengthy drama can go for korean version but those doesn't like lengthy one can go for this . I liked the story so that's why choose to watch it.
I given 9 for the story because second last episode was bored and last episode finished in a hurry .Atlest they should show their marriage and their life after marriage ,so I think they can add one more episode to give perfect ending.
