The hero and the dark lord have both disappeared after their battle, making everyone think they both perished. In reality, they are living on a farm, living the life of their dreams.
The way that I've read a bl kinda similar to this recently but cannot remember the title for the life of me. Basically the hero spent forever climbing this demon kings castle a bunch of times but at the final battle they decide to get married but like everyone else is like ???? Wtf this cant happen??? You're supposed to kill him not elope??? And since everyone was against it they escaped to earth on halloween(im like 80% sure it was halloween) but cannot use their powers there so they live as an ordinary couple(well kind of) in a one room apartment. The story starts with them escaping i think and the rest is them in the human world. But the story doesnt get rid of magic. Ex: the demon kings i think little brother tracked him down and got stuck in the human world too. Oh and theres like this wizard whose also in the human world and found them and helped them adjust to life in there.
It was driving me mad so i went and found the title!!! Its complete at 8 chapters(unaware of any side stories):
Yuusha to Maou no love one-room
Or
the hero and the demon lords one room of love
