>>103334323Ina is straight or at least has refused to do yuri pandering, which implies that.
I honestly don't know about Flare. It seems that she met Ina IRL at some point and became obsessed. Either Ina's incredibly attractive, or there's something else.
(I've seen an old picture claimed to be Ina and she looked completely normal - nothing that could explain Flare's obsession.)
