I was reincarnated into a romance simulation RPG world as a fairy whose role (planned) was to beg, "My world is in danger, please go to another world and defeat the Demon King, Hero!" But then I got captured by a boy who is destined to become the Demon King (slightly overpowered and slightly yandere).
*Contains very subtle sexual content.
Unable to escape the boy who suddenly came onto me, I changed jobs from housekeeper to lover to wife.
The story is simply that I might end up in a position like a close confidant of the Demon King, fighting just before the final boss.
*A comic adaptation is currently being serialized on Young Champion Web (Akita Shoten).
