I was quite enthusiastic about this drama. I love the main cast specially the 2nd male lead. However I didn't like the main story. I didnt get hooked by it.

The idea of 2 dimension with 2 Korea is actually a very nice aspect ! I really love that part. I didn't like the rest. I think I am getting tired or unrealistic love story or cheesy love story.
I don't recommend it but I always think people should see by themselves!
I think people see big name and just get bias...
There were at the beginning very nice and mysterious part such as the ID card in the 2nd dimension ! But you kind of get bored of the whole thing.

But I love the 2nd male lead playing two character ! I watched a bit more thank to the 2nd male lead
