I don't know for sure. The ending of such a manga can be quite unpredictable and might not have been revealed yet. You could try discussing it with other fans to get their speculations.
I'm not really sure if they end up together. Different people might have different interpretations. Maybe you can dig deeper into the manga and form your own conclusion.
The authors of the best beat novels include Jack Kerouac. His works are very representative of the Beat Generation. He was known for his spontaneous prose. Then there's William S. Burroughs who had a very edgy and experimental writing style in his novels. And don't forget Allen Ginsberg. His poetry - like prose in 'Howl' was a huge influence on the Beat movement. There are also other authors like Richard Brautigan who added their unique voices to the genre.
I think Ursula K. Le Guin. Her works often go beyond the typical tropes of sci fi novels. For example, in 'The Left Hand of Darkness', she explores gender in a really unique way within a science - fictional setting. Another one is Philip K. Dick. His novels like 'Do Androids Dream of Electric Sheep?' are so complex and thought - provoking that they can be considered to 'beat' many regular sci fi novels in terms of depth and originality.
