That would be kind of like incest in a way. Cause once you marry someone from another family you two will become family also. But if your own family marries "your family" from their family... it would be kinda weird isn't it
That wouldn’t be incest none of them would be related they’ll just have the title of in law (if marriage) but lots of people have been siblings and dated other siblings especially twins, twins will date other twins
Ur not alone lol
It's like ki and kki r made for eachother
I think I am the only one who ship whole ki sisters and whole kki brother ٩(๑❛ᴗ❛๑)۶
