my actual thoughts on the story:

it's loaded.
I think it's designed to speak to guys in their upper twenties and press on the right buttons. fear of responsibility and commitment, escapism from the world in a bang, feelings of not being genuine in the world, and mostly, guilt about all that. the story is making us identify with jagaski and then pulls the rug under our feet by reminding us that his behavior and desires are pretty dumb and juvenile. it constructs a situation that allows a fantasy to come to fruition, but reminds the audience this fantasy is full of shit and that it hurts everyone around.
