[Nonhuman 1v1 + gloomy, obsessive yandere] Cold-faced, spiteful nonhuman husband × traditional, conservative Earth wife
How do you properly raise a female human?
The planet Dokado is facing an unprecedented fertility crisis. To restore its birth rate, it has set its sights on Earth, far away in another galaxy, where life reproduces more prolifically than anywhere else. Humans have the highest reproductive capacity of all.
Hesier, Dokado's strongest God of War, was the first to be sent to Earth on a mission to gather intelligence. He chose to form what was supposedly a social relationship with a carbon-based life-form from Earth, one with zero combat ability and limited intelligence.
Based on real cases, he wrote A Guide to Raising Female Humans for future generations. Since his wife disliked being called a female human, Hesier briefly changed the title to A Guide to Raising an Earth Wife.
Note: The story begins on Earth and later moves to outer space. No angst throughout.
