Well that sure escalated quickly. But we really going this route? Really? I knew all along when they first said basically all the men are gone few chapters ago, but man...
somehow a farming manga always get's you HAREM, a real one, not just a tags (another farming title is Isekai Nonbiri Nouka). and he married them all, not just making babies (that's the important thing).
but i only read 2 of them so far, idk if there's any other
Marriage irl is actually very simple and you can cut out almost all the fanfare and costs. All it really needs is your signatures on a paper, and pay the processing fee. No diamond ring, no expensive ceremony, no family war... just two sigs on a paper and pay the fee.
