A mysterious young man who moved in from who knows where and lives alone, rarely leaving the house—even his neighbors know next to nothing about him. Devoted to his art, he often stays up late hunting for exactly the right notes and rhythms, and that obsession with precision carries over into the way he lives: he has no time for anything fussy or complicated and cares only about what’s practical and effective. These days, he seems to be worried about how to make a living. To open up more ways for people to hear his songs, and to solve his day-to-day problems, Aza weighed every option and finally settled on livestreaming.
