Sure they met when they were kids, but she only been in the house for a year and som months before the parents died. It might feel like more cause of the whole back story before she got reincarnated, but the total years she lived in that house before they moved to the other house was two years and two to four months. So she didn’t really have a brother/sister relationship with the oldest compared two the other two, because she only lived in the same house with the oldest for two years. Two years is not enough time to build a brother/sister relationship, especially when both parents died and other deaths just in those two years.

That's not what "growing up together" means... If they don't live together while they grow old how is that "growing up together"? Two years are not enough to grow a sibling bond with someone... Especially when in such a short period of two years Eugene's parents die... Just say that this relationship doesn't seat well with you because of their status as siblings (on paper). That's totally fine, we can all think of it however we want but claiming that they grew up together when they obviously didn't it's just wrong?
if they didn't grow up together it wouldn't bother me a much ┗( T﹏T )┛
