I live in a world unlike everyone else's.
In everyone else's world, I'm a defender of order, a hero who saves the world, leader of the Dawn Alliance, commander of the Dragon Knights, chief archmage of the Scholars' Alliance, a federal marshal, and a prince of both the northern and southern empires.
In my world, since there are no computers, online games, or consoles for me to hole up with, I can only build a harem while saving the world and play real-life RPGs to pass the time.
The irreverent version:
This is the story of a transmigrator who thinks he's a tech geek but is actually a total shut-in, building a harem without shame while saving the world on the side.
This is the story of a lovable shut-in who loudly calls for love in a loveless world.
