First of all, I was quite hesitant to watch this, because I was quite disappointed with Memories of the Alhambra, which was also written by the same writer. But I am so glad that I did. The story itself is told with great layers, and it is quite obvious that they did manage it well enough that it does not feel dragging like many series. So I can say it outright, the story itself hold the series high above.

Now to the nitty gritty. I find it in the first few episodes they 'recap' a lot of time. As someone who is binge watching this show, I kinda get annoyed because I was like - I just saw that in previous episode, no need to reiterate it. As the episodes go on, they do it less and less, and in fact when they have some kind of 'recap', it was because they are adding layers to the story - which is great.

The rules of travelling. They established at first how Yeon Joo travel into webtoon and how she exits. Ok, good. But then after awhile, this has been confusing as she was able to easily go back and forth. And then you also have Kang Chul, who can easily interdimensional travel too by will. I'm just annoyed, since they should have clearly make a rule on how these characters able to travel. But I guess they have to take leeway on those things to tell story.

It's funny how the series always draw car and syringe. Clearly the car is a product placement, I would have get a plane or helicopter - or why can't they just teleport people using the tablet? The evil doppelganger of the dad was able to get in and out of the studio with a screen, why did the main characters decide to use cars to travel? And seriously, you have so many cars passing by, none of them stops to help a bleeding man on a bus stop? Is that for real?

The ending was great and satisfying. Actually the show gave great setup and conclusions half way through at episode 13 where they can easily finish the series. So for those who are fans of the romance side of the series, I think it's very satisfying ending.

Music is great, I have no problem with it.
