As someone who had read the novel before, I can say that I enjoy this drama. Is this drama good? The answer is no. Is it the worst? The answer is also no. There are other worst ones.

But I can understand why this doesn't work on others. If you never read the novel from beginning to end, it's really hard to enjoy the drama itself. Actually, the actors in the drama did a great job in portraying their characters, because that's how they're written in the novel. The characters in the novel all have the same paper thin personality as in the drama.

The worst thing is they adapted the word by word novel into the drana, without changing anything or adding the aspects that makes visual storytelling more enjoyable. That's why I rated it as lazy storytelling. The drama team just slap the sentences in the novel onto the drama, without giving it a soul, making it sounds so boring and anti-climatic. When I read the novel, even though I think it's crazy, but since the novel has some kind of background information on why the characters do what they do, but in the drama they didn't bother to do that.

I know how the novel ended so I do know what will happen next, and I also have the privilege of knowing what they're thinking so I'm not that annoyed like others.

My verdict:
This is a watchable drama if you think you have nothing to do and you have a lot of time to spare, and you also no longer has other dramas to watch. It was not absolutely terrible either, and I actually grow fond of the main couples, despite their weird background. This drama is perfect to watch when you are doing something else, like working, doing laundry, etc, as you don't have to focus much to the drama.
