What ever happened to enticing someone

Technically he said fiancé not marry. He needs a fake not a real lover (yes this is a shoujo so they probably will end up together but that’s not the point)

But yes I agree with you, he should have started with the carrot first XD

What he did was the best solution in that situation...

The carrot is usually what you offer before the stick. And I definitely don't think that was the best solution.

However, in shoujo it's often seen as too "calculating" if the heroine were to agree to do something for financial gain. So the male lead usually threatens first to show his "dominance" and so that she can remain an innocent who is being forced against her will.

This way she remains like a child. Because she did not choose to help him, she avoids traits like cunning and working for her own self-interest. The male lead can't see her as a schemer because he made her agree. He made the decision. She didn't. It strips her of any dark traits, yet also takes away complexity.

But I still like it anyway. I mean this is just for entertainment. I just wish sometimes in such stories like this the female lead had to face real decisions and weigh if something was worth it to her.

He does what is best for him and the female lead just goes through the story all "la-dee-dah" and "tee-hee~" because she has to be kept an innocent.

Yes usually, but it's not always the best thing to do, specially now when the one you are making the offer to have something they can use as a threat. Even if they offered her everything she want now, what proofs did they have that she wouldn't use what she know later on as a threat to get more? Also you have to take into consideration that's she's extremely poor, with peoples like that you can never be sure how they would react if all of a sudden they see a huge amount of money. So yeah, starting with a threat was the best in that situation, it scared her and showed her that her knowledge wouldn't help her in fact was that knowledge was bad for her instead and than at the same times gave them a safety net.

We as the readers know that she's innocent and never would do anything like that, but they know nothing about it, they did an investigation but you can never knew another true personality so easily, some peoples can hide themselves their wholes life without anyone else realizing their true personality.

Starting with a threat is almost never the best in a situation. People are much more reliable when they feel they've chosen to do something than when they have been threatened into it. People doing a job because they feel they'll gain something are more reliable by far than someone doing it because they're scared of imprisonment.

In fact, because she's poor they'd be more likely to try money first on the assumption that she would happily jump at their offer. They'd also have better leverage over her.

I absolutely disagree with your premise. That is not how things work. And they would have to be the world's dumbest people to live in the society they do and have no sense of whether they can make a deal with someone or not. People like that size up others and figure out what their interests are. The only surprise is when people don't act as they expected them to.

The surprise would be if a very poor person turned down an offer of a lot of money.

People who live in such high stakes political words are very adept at figuring out people. They have to be. It's their bread and butter. It's do that or die.

Also the whole point of having him threaten her is so he can be the "dominant" male lead. That's why it's so common in these stories. The real reason why shoujo heroines are rarely made offers is so they can remain "pure", innocent, almost child-like characters. It has nothing to do with "they didn't want to offer her money because they don't know how a very poor person might react". It's because the trope is to proof that she is "not like the others".

Shoujo heroines like her have to be kept as pure girls who don't make real decisions. If he offered her money and she accepted, she would be "like the others" and if she refused she would be "stupid". To avoid this nuance and complexity of her weighing such a choice, the writer has her coerced. Then she can remain pure because it's not her fault. There was nothing she could do but be helpless to her circumstances.

This lets her be a damsel who slowly melts the prince's heart through her innocent nature.

I don't mind. I read these stories anyway, but it's silly to act like we don't know why its being done this way.
