Yeah that's what I was thinking, like the Duke doesn't know what she did to her body and he doesn't know she knows how to reverse it and that it's not doing her any harm. All he knows is that he doesn't know what's going on with her, whether its for the purpose of getting pregnant or not. It's true he never gave it much thought but I think the one Butler dude bringing up that it could be some sort of disease or illness really shook the Duke and made him realize the situation. He's just dense and before this he was uninterested in this kind of relationship but now that they're this far in a lot of things are starting to click.
This makes a lot more sense when we bring the butler into play when it comes to the duke's mindset. Considering he didn't have an opinion on //that side// her health until the butler broke his promise because he was worried about the duchess' well being
I just wished it was conveyed better and wasn't such a pregnancy central topic. (Not saying that having pregnancy is bad just that the execution of the story and uncommunicative partners really pushed this narrative out of proportions in my opinion)
Luckily nothing life threatening and I just hope they come to the middle about what they want in the relationship and the next step they overcome NO MORE SECRETS YOU TWO
I WANT YOU BOTH TO TELL YOUR SOB STORIES TO EACH OTHER AND GROW AS AN EVEN MORE LOVELY PAIR THAN YOU ACTUALLY ARE
Moving forward, they will be pretty good about communicating. There will be small moments when you wish they would talk instead of sitting there with questions but its nothing bothersome. And the never let crazy manipulative people interfere in their relationship. They trust each other a lot, its cute. It's why I love this story. There isn't any unnecessary drama. And it's not forced to be uncomfortably long.
So like I'm glad he told her the reason why she won't be able to have kids in his family, buuuuttttt
Why make her be able to have a period when in your mind the likelihood of her getting pregnant is zero
Like why give her hope when you don't want kids and explicitly put that in the contract.
Idk that's my only beef with this webtoon cuz I know, as readers, we know that if she follows the advice of her past life she can get pregnant with the duke's child, but they as characters don't know that.
