Also this would have been fine if they grew up separately , didn't know who each other were when they would interact and got closer. So then it would also be kind of like a mysterious thing and you know if they just didn't refer to each other's brother and sister. I'm pretty sure even when they're both younger, they know they're not blood related. And I get why would make sense that they would refer to each other as brother and sister but it's still just not a good choice on the writers part.
Agree
Don't really care if that count as spoiler cuz waste of a good story and art... From what I remember they aren't blood related if I'm wrong they half sibling or somethin. Either way sibling romance are always a stupid waste of time.
