Because they naive AF. How stupid can they be? The maid clearly said not to trust the Duke, despite the twins having clearly said the maid was honest. Like?!?! Plus, letting their 5 year victim hood define them when they’ve lived basically an adult life for 80% of their mental ages, it’s like how are you not taking advantage of your mental maturity and planning for world domination? How can they not see the imperial family kissing their asses but take the duke’s ass kissing at face value. What a joke

and yaknow what other people are sayin?
"in their past live, they died at their teens age and reincarnate so they technically doesn't reach adulthood yet so ye"
and I'm like... I'm pretty sure, even primary school kids these days are better than that and also they're not that naive at least in my country

I am copy pasting my previous comment and read with caution especially for younger audience, some information are quite disturbing.
They were 18 years old before reincarnated. At that age, your brain is still developing, which is why teens phase are often called the rebellious phase. Quite literally your brain is still changing (you can google this, when is your brain stop developing and different mental moral development stages). Now imagine, if you are still living your teenage years, and you die, then reincarnated to an abusive mothers, and unkind environments (not getting proper food, water, exercise, education, etc) for 7 years. Your brain are still not developed at the time, so forget your mental age, you are essentially regressed to being a child. An extreme example of this is Genie https://en.wikipedia.org/wiki/Genie_(feral_child).
I have watched a documentary of 50+ years old men, were sexually abused when he was a boy up until 14 years old, could not cope with it emotionally even after 50 years old (source: watch “tell me who I am” or read this https://www.latimes.com/entertainment-arts/movies/story/2019-10-21/tell-me-who-i-am-netflix-documentary-child-abuse ).
Let us say for sure their mental age before dying is 17, but we still have no further information from the twins previous family. Gene is one factor that could affect your IQ - your mothers nutrition when they were pregnant. The second factor is nurture or the environment the twins live in. Experiments were conducted before in the 70’s to find out how can nurture or nature affect child development, which ‘three identical strangers’ documentary look into this https://www.latimes.com/entertainment/movies/la-et-mn-three-identical-strangers-documentary-20180702-story.html . The experiments were still not published because it is not ethical in today’s world, but basically I can get the give you the gist info from the documentary. 3 babies (triplets) were born and situated to different household. One the dad was busy but loved the boy, second dad loved the boy and the dad’s world revolve around his boy, the third dad is very hard and harsh with the boy with very traditional teaching. Later one of the boy from the triplets commits suicide, and you can guess which boy it was.
Human mind and behaviour is not easy to deduce, you can be rational with your judgment in your respective individual settings, but even that individual settings are depend on your family gene and more largely depend on your environment when you grew up. I’m sorry for the information dump and thank you for reading this up until now, I hope this information is helpful.

If you are interested in adolescent brain development, I found a paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3621648/ that can explain more on this.

Thanks for the materials.
Now, genuinely curious, do you think the inconsistency of their wariness stem from being transformed as infants and the trauma too?
We can see that the twins are wary bec of what happened and what their father's inaction did.
And although they actually trusted the nanny bec she dished out cold hard truths as opposed to other people and the other kid due to being in the same scenario as them. As opposed to the little interactions with the Duke they seem to not be wary of him?

With all due respect, the examples you give all has the assumption that the abused children knows of no better conditions. We don’t know what their past lives are like. Sure. But if they’re so distrustful of everyone, they should be just as distrustful of the antagonists. I won’t go into the dualities of nature vs nurture, or the implications of a blank slate, but even in their infant hood as newly reincarnated children, they should not even be able to compute worldly information with an infant brain, if you truly wish to apply child psychology into this. All that is to say that their circumstances unique, but even the author doesn’t go into mental capabilities, besides the trope that to other characters, they appear more mentally mature than their ages. I don’t deny the implications of a rough childhood; better examples imo would be children rotated constantly through foster care. But the twins’ shoddy character judgement is a glaring plot hole that delegitimizes whatever trauma trope the author uses to perpetuate misunderstandings that could easily be resolved with proper communication.

I am giving you examples of what could happen, before and now. Does not mean that my info can really be what happen, its just one way to look at it, because fundamentally you are asking are they really 25 year old mentally? I heard that the novel, the twins doesnt act like this, they don’t even talk to people initially at all, the manhwa brought changes to the conversations and characters, which is why as you suggest plothole happens,

It honestly ain’t that hard to say you got kidnapped and omit the part about who you think kidnapped you if their anonymity is essential to saving your ass. Nor is it hard to even say you got kidnapped and ask SH to keep it a secret because you were threatened. Like use some common sense Nakyum????? Is your brain only used for painting?? Likewise it ain’t hard to see Nakyum’s injuries, and believe his own servant’s accounts of Nakyum’s motivations? The author is clearly just dragging this on more than necessary and only the next chapter can redeem her. The dysfunctional communication trope can only work for so long. Not even k-dramas abuse this with the fervent frequency the author does.

I’m actually super disappointed in the writer right now. We are 62 chapters in and again, nothing has changed despite the miniscule progress they both made. Super disappointed.

Hahaha. I also always come here for the interaction. I find here more interesting than in the main platform.
Maybe because of the Genre that is not too acceptable on the society that in main platforms, the comments are mostly closeminded.
I am not saying there aren't here as well. But atleast most people here you'll have a fond conversation and not one-sided.

Word; even now I still find it this a bit Stockholm syndrome-y, but the discourse on their interactions are more interesting to read here. Still gotta support the author you know?
But I think I might take a break from this after the next chapter because man it is brutal to invest in 30 chapters of progress, only to revert back to stage 1 again because of their dysfunctional communication.

With SeungHo saying he’d rather die and kill those who torture him, plus with Nakyum’s potential assassination plot, I feel like this will end with both SeungHo and Nakyum dying in the period timeline, with each of them discovering the other’s feelings a bit too late. I do have a hunch the author will reconcile them in a modern timeline through their reincarnations though; whether they remember or not might be a bit of a stretch.

The only reason he hasn't told Lami the story behind his hand is because it reveals his naivete and foolishness that even his father could foresee. He is traumatized yes, but ultimately ashamed by his gullible character. He was naive to believe in the goodwill of people, and to think the second prince wouldn't do anything severe. He will be Lami's (and their family's) downfall, I can see it.
Yes, the non-consensual part is an issue, and the redemption arc is what I’m here for. The sex scenes are hot but the rape element is not. Yes, Seungho is a horrible person and abuser, but do I still find him physically attractive? Unfortunately yes. Would I want for him to be a partner for someone I know? Nope. Does he deserve Nakyum after all he has done? Nope. But somehow, the author gives me hope for what they could be.
I love the micro-expressions the artist portrays; especially in chapter 69. You can tell Seungho is having a relevation without having the author literally spell it out in thought bubbles. Some of yalls need to read between the lines (or in this case, panels).
Same I'm just here for the character development. I know Seungho went through some shit in the past but that still does not justify his actions. There's something in me that hopes Nakyum will never forgive him but there's also a part that wants them both to be happy. I just wish that the ending will be satisfactory for them and for the readers.
