I can see that being an isekai manga. Say, by the person who did Spice & Wolf?
Oh, by the way, check out Barefoot Gen. It was written by a person who was a boy when the atomic bombs hit Japan. It covers the post-war period, including the corruption and day-to-day life of a shattered Japan.
I was raised in rural territory, having no neighbors or childhood friends. To say the least, figuring how out to socialize is a bit...problematic. Is it proper to deny sharing a first name when asked by a random dude who fist-bumped me at the library for just telling him the opening time? I do not know.
Getting out of my shell is going to be weird.
