to be honest there is not much difference between the original and the korean version but particularly i liked the korean one more.

the cast is very good and I thought the choice of Park Hae-soo as Berlin was brilliant, the character suited him so well that it made me obsess over him for a week lmao.

I liked the issue of the Korean peninsula and I think that if done well it can be beneficial to the story.

It's important to keep in mind that this is a remake so don't expect major changes to the original plot.
