As a remake of the famous "You're beautiful" this japanese version was fair enough. Honestly the story is almost untouched except little things that i liked them adding it especially at the bigenning and at the end. The korean actors are a little better than the japanese ones but i loved Mio better than Go Mi Nam. Some characters differs a little from both versions but what insures me the most that the music is the same i mean of course they translated it to japanese but it was a nice move i was afraid that they would change it. Finally, i prefer japanese over korean when it comes to the language issue so to end this i would say that each version is nice on its own way and let's not forget that the japanese version was faithful to the original one.
