I like this a lot and very touching. Made me laugh and cry throughout the whole series. The leads look good together and the chemistry between them is top notch.
First of all, the story is super duper good, the sad scenes can make your heart ache. The leads never annoy me one bit, the story behind every character is very well done.
And the music is really good, I will download it later. Even though I dont understand some lyrics, it makes the scene more touching and dramatic, it fits really well.

This will probably be one of those series that I will not get over with. I love this. I've watch countless of dramas and kinda find them similar and this is not one of them, this type is one that will make your heart remember.
