She told him that a divorce scandal may be bad for his career and he risks not being reelected. It was to protect him, that's the excuse she gave for her refusal.
At least that is how I interpreted it when watching.

There are a few cracks in the internal logic, though. Like this crazy idea of agreeing to taking the little king for a ride in a sports car - totally incompatible with the smart FL we've been shown so far, and especially after the prince's warning in the ramen scene.
But, most importantly, it's their marriage plan that makes little sense. Their motivation is understandable, but the actual plan is very vague and what happens after their marriage is problematic.
She wants a title so that she can upgrade her social status and become head of the Castle group. But what will happen to her business if - as we were told in the last episode - royals are not allowed to have businesses? And how easy will it be to divorce, especially in a country like Korea, where even for regular people divorce is frowned upon?
As for the prince... His motivation is, since he has to be married, at least get a wife who will be on his side rather than a Queen's puppet. So far so good. He already likes her looks and personality, so even if he's not deeply in love yet, he's okay with her, she's better than any other option he's been presented with. But if he divorces, his image will be tarnished.

Very good points.
(Divorce is viewed very badly in Korea even for regular people, as we know from all the dramas we've watched).

Just sleeping, though.

However we are told that whenever he tried his hand in business it wasn't successful. Some people are just not made for this job. Shouldn't the best one have it?

The details of the plan are not very clear to me. If she's not allowed to do business during that period, who will take care of her company?

You cannot call it spoiling when no one knows how it unfolds or how it ends. When you state information available to everybody without even watching the drama, it's not spoiling. If the information comes from the official summary, or from the character description on the official website, or from an interview, as in this case, would you accuse the producers of the drama of spoiling it for the audience?

However this is not insignificant in my opinion. You may disagree all you want, but I'm entitled to think like I do. And I think this plot device was a bit lazy, because this decision is inconsistent with the smart woman we've been shown so far.
Even if the others okayed it, she could and should have refused since she would (also) be blamed in case anything happened and the stakes were too high: any wrong step and her already shaky position could be threatened.
Also, she very well knew that the prince wouldn't have okayed it either, after the ramen incident, and she could at least have called him to ask for his opinion.

Even then. She would stay married for a little while, before divorcing. So she would have to transfer the business "temporarily" to someone? How would that work and how would that someone give it back to her? Or maybe she can still be the owner but without running it (for that period)?

Okay, but even without a special seat, you'd put the child in the back. The place near the driver is considered the most dangerous. And the whole idea... I get why they did it, plotwise, but it's a bit stretched. When the Prince told her to not even give him ramen because of the remote possibility of having an indigestion and she would get blamed, how could she be so careless as accepting a car ride, alone with the child?

One more reason why it was a bad idea to begin with.

I agree. That's why no one puts a child in a sports car.

The royals are not shown to have decisional power. As it was clearly stated, they have to avoid taking sides in politics and even in sports, they are to remain neutral in everything. The "work" is mostly social appearances and charity - just as the European royals of today. The difference is not in royals but in the nobility - the influential families coming from the Joseon yangban - having taken all the strategic posts in public life. Which seems to be true in Korea even in real life, even without the need for monarchy.

It's an expensive production, Subway and Copico must have given loads of money.

That's why the OP said "judge it COMPLETELY".
That said, I think that 4 episodes are enough to set the tone. How much can it improve? It can, but I don't think that it will become something different.

There is a saying in my country "He who loses in card games wins in love".

Kids that age have to go on a back seat, not the one near the driver, and on a special child seat. And some other person should have been at his side. So a sports car is a no-no.
The whole thing was a bad idea and, tantrum or not, shouldn't have happened, regardless of the tampered brakes.

Good point.

Well "decorate" is a big word. They added a library and a second desk that seemed Ikea stuff and didn't go at all with the rest of the decor.

You're welcome to have your opinion about such behaviour (it does seem to work a lot of the times), but my point was that we see it done by both men and women.
