I know this is wrong but I don't actually give a fawk, it was great.
It isn't wrong so much as taboo. Interfamilial romantic relationships are frowned upon for biological reasons. If it's between the opposite sexes and a child is born it can result in the child having numerus birth defects, genetic diseases, and other such things. That's why it being between men isn't nearly as bad because there's zero chance of pregnancy.
Bruv, I sure know what might happen to a baby born between two blood related people. Also in ancient Egypt Pharaohs would marry their sisters to keep the Royal lineage.
Leaving that aside, I think sexual attraction between family members is something repulsive, like, first of all: How? How can you possibly feel attracted to your brother?
Personally i could never.
I still recognize that if two siblings fall in love I can do nothing about it and I'm nobody to separate them.
Anyway, yea, marry your sibling and having kids is way worse than just fuck your twin brothers and not giving life to a poor kid with no fault.
At the and, I enjoyed the story so that's fine.
I completely agree with you and I wasn't trying to make it sound like you were ignorant on the matter, I just felt the need to point it out. I, personally, have six brothers and two sisters and could never imagine ever, ever, no-matter-what-NEVER being in a relationship that was anything but purely platonic with any of them. I just sometimes think that it would be kinda heartbreaking to fall in love with a sibling. It's taboo and usually can't be. It isn't your fault if you end up loving someone you really shouldn't have. The heart, is after all, a fickle and incontrollable thing. And, yes, the story was good. I enjoyed it a lot.
I want Cain to be happy, however, I also want to see Yahwi fall in love with Jooin and become a couple.
