@cherokeemoon They are all related by blood, sure, but they are all distant cousins. I mean, all humans are related by blood because we share the same ancestor/origin(the fact we can produce offspring with each other is evidence enough, for the most part) and this is the same concept, just on a much smaller and more family specific scale. Some of them might share the same parent or grandparents, but it's likely that most of them are several generations apart. Romance in this context is perfectly fine.
