I adore this so, so much, it's everything I could have hoped for with this prompt and more.

I really enjoy your writing style, it has this very deliberate weight and really nice pacing, and so many of your turns of phrase are lovely. But what I like best about this fill in particular is how thoroughly it alludes to both Furuya and Abe's pasts, without ever bringing their backstories out into the open. I love that it's present as this weight upon them, this thing that causes them to rub each other's nerves where they're raw without quite understanding it, but I love best of all that it doesn't stop them from being a battery who can work together.

And the handholding! As much as I adore this in general I think I love that the most with specifics, because it really makes me think about Furuya at Nishiura and the ways in which that could be really really good for him. It and everything after it make me want to believe that in the end, this battery will be good for Abe and Furuya both.
