i'm sorry anon but i don't have much nice things to say when it comes down to this ship. the dynamic between these characters are too different to what i particularly like when it comes to shipping akishinji and akihamu separately (i don't like shinjihamu admittedly), and i find them even less desirable when it's just either of the men fighting over hamuko's attention. the latter is what i typically see of these three when shipped romantically together. the general gist is that regardless of how they'd all be shipped together, i still get more out of interacting with my favorite ships separately. i think the only instance in which i could find this trio remotely interesting is if akihiko were to be the one in the middle, but it's not really a poly ship then, is it? so i wouldn'y go out of my way to classify it as such. though if you enjoy this, more power to you. i'm quite fond of them as just friends anyways. hope i didn't come off as too harsh here.
