The longer this goes on, the more I realize that there's likely NO POSSIBILITY of a good ending. Dude basically got isekai'd into this world and he's a golden unicorn, someone whos quickly becomes attractive and friendly to a large group of girls who have only ever imagined someone like him as possible in their fantasies just appeared from nowhere. I don't believe for a second that a harem is at all possible, a lot of these girls, from their own thoughts, would likely attack and possibly do other even worse things to the other women for the chance to be with him. I feel like this manga doesn't really have anything remotely approaching a happy ending and can only end in heartbreak for a ton of people. Just my thought on this world.
