This is the question you should be asking yourself when you start watching this drama. If you're going to watch it half-heartedly without paying attention too much to the details, you might find yourself getting lost which is exactly what I didn't like about this drama. Below, I've listed the following reasons which made it seem like a drawn-out experience for me.

1. There is too much information with little to no time to process what is happening.
From the very first episode, it was quite evident that this would be a problem that I would be encountering throughout the drama. If you've watched it, I trust that you fully understand why I am saying this. They give you the general gist of the situation with not much clarification, they tell you one thing without explaining much of it.

This would've been a lot better if they didn't force you to process so much information in such a short time span.

2. They make it seem so complicated when in fact, it is not.
Finishing the drama, and understanding its general gist makes me realize how simple the entire situation is. It took me through so much when it shouldn't have.

3. The second half of the drama was just, too much.
Everything comes out of nowhere, suddenly, the male lead is doing so much when he came from such an incapable background.

Again, this drama is totally dependent on you. If you can keep up with the force-feeding of information, then maybe you should watch it. I'm only describing it from my point of view.
