Ikr? I would find it extremely hard to fall for someone I've grown up with all my life and viewed as a sibling the entire time. It feels like a natural barrier for a romantic relationship, but that's just me. (I come in peace, please don't kill me)
But the funny thing is, they didn't grow up with each other their whole life and the ml even don't view her as a sister. So in a sense, these two are possible as a romantic couple (if ever the author permits, if not, im still okay with it.)
You make a fair point regarding her age on arrival and their separation. I would guess this is probably how they may end up as the main couple.
[clears throat] yeah um i get that they are... the fl and ml but the amount of people saying that step-siblings aren't real siblings when it's extremely invalidating is pissing me off. pleasepleaseplease think before you post a comment. i'm not here to ruin the fun, i actually keep up with this series :0 but please be a little more sensitive:D
