1st off there are only 2 ways to get pregnant, having a doctor do a procedure with donated sperm, or sex. Think you idiot, in since she most likely didn't have money to spend on that kind of procedure back then, how else do u think she got pregnant! why would she be a virgin when she was pregnant! its possible if you know what you are doing and are precise as a scalpel to have sex and not have a female's hymen break. true fact most of the court cases that were dismissed where it turns out the woman was raped, were dismissed because their hymen's where still perfectly intact. how about you look up a lot more then specific things when you're trying to look smart. dumb ass, you're like that ponytailed asshole from good will hunting.
they're rich now. but they might have not always been rich. and you forgot about the double pregnancy thing, the fact that the mc was adopted so this is technically not incest.

unless the mother isn't part of that family and the grandma is his dad's mom or his real mom's mom.

and that despite those things that wouldn't happen irl, but its not like this is a vn about fern-gully, dbz, or some other made tp sci-fi universe. it still mainly close to our real universe and has some of our irl rules and logic in it.
So you fucking retard, before you start attacking someone, read what you're responding to. When did I write anything that would be directly against what you're writing?
It was mentioned several times in the story that she was artificially inseminated and gave birth by c-section. Where is the reason for the hymen to be damaged? (I'm not a doctor, maybe artificial insemination doesn't work without a ruptured hymen - you're obviously not a doctor either if you speak like a neanderthal and have trouble understanding written text) So the only contradiction in the story is actually just the phrase "virgin womb"
It is also mentioned several times in the story that Ophelia is fucking rich and practically rules the entire city. It wasn't mentioned that she was poor before...
MC was not adopted, his parents died, his father is also Sophie's father, so there is incest. MC fucks his cousin, his mother's sister and his grandmother, so I assume that is incest according to your standards. Only Jamila is not his relative even though he calls her Mom, that is also made clear at the beginning of the story, where he does not call her Mom.
And still, its porn game you must have poor life when you try find some unbreakable logic there
But I'm afraid it's pointless to write to someone so stubborn. Adios
