imo they werent raised as siblings at all, they were taught to kill each others from a young age and he knew from the start they werent related and she was too busy trying not to get killed to start having any sibling feelings till she knew the truth about herself
but from the outside view it IS weird, from their view, not so much
It just irked me how they were raised as siblings and ended up as lovers but besides that I love it..
