Are Interspecies Relationships taboo or not?
It's something the narrative seems undecided on at times. For the first 60-or so chapters of the manga they are treated as something society frowns upon...But by the time Haru is attending college they're trendy and "in" all of a sudden?
Did I miss something?
Because I'm pretty sure during the Murder Solution Arc the way society views Interspecies Relationships was a sticking point between Legoshi & Haru. He wanted them to be open about their being an item but Haru was against it. Which is part of why he questions if they are actually an item.
Yet when we get to the Love Failure Arc we see Ako and Eardo openly dating at Haru's college and no one cares. It's treated as fashionable and desirable rather than taboo & shunned.
