>more than two blood related siblings getting together
Irrelevant. Opposition is opposition. You keep getting hung up on the relative difference of BR being greater than NBR, which isn't what this conversation has ever been about.
>the taboo will always remain even after they've decided to get together
Not really. Any taboo would be incredibly weak. And, as a romance, it's EXTREMELY boring. Two people meeting in their 20's and realizing that they're related isn't a real taboo. If they didn't grow up together, it's no different from NBR
