Even characters in story are frustrated with how undefined the relatiionship is.
I can't help wonder if they have a sex life with each other. We know Sakurako has a sex drive but it has always been questionable about Kasumi.
If you read yukiko’s oneshot “Tomorrow When I Wake Up”, it indirectly implies that they did have a sexual relationship and possibly continue to have.
I think it’s decently important because as Hinako says, the label of ‘platonic relationship’ doesn’t quite fit them.
Given how complete Futaribeya is as a story and how insistently yukiko has repeated saku’s desire not to be bound by labels, I’m inclined to believe that that’s the intention: that Sakurako (Kasumi doesn’t seem to really care) doesn’t believe the words ‘dating’ or ‘girlfriends’ fits them.
But PERSONALLY I am desperately headcanoning that this is Sakurako trying to convince herself that she’s happy with how things are. I am going to read too deeply into it but I want to believe that the reason she has this little monologue about change on tap is because it’s what she tells herself. I would love to think that the reason yukiko includes Hinako mentioning how scary the chance of losing the relationship is, is because that’s what Sakurako is most afraid of.
