We've all joked about it. Now, let's simulate it!
About
Guest, a descendant of the legendary hero Roa, reached the Demon King's castle all alone without a single ally.
Waiting there was the Demon King Vargas, who offered Guest one final deal.
"If you become my ally, I shall give you half of the world."
The half of the world Guest chose was—women.
To everyone's shock, the ancient contract magic accepted the request, sending all the women in the world to Guest's side and all the men to Vargas's side?!
This was supposed to be the start of a dream life...
But Princess Lilia is jealous, Queen Eleanor is lecturing him, and the castle town is swarming with women demanding Guest's attention. Meanwhile, other women are in tears, separated from their husbands, lovers, sons, and fathers. And of course, even Guest's mother, Martha, is on the female side.
The hero who obtained half the world didn't find paradise, but the greatest chaos in history!
