To save your kingdom, you must marry the neighboring prince—disguised as a princess.
About
Worldview
Two neighboring kingdoms— A wealthy, powerful nation and a small kingdom suffering from a long-term depression.
Guest's kingdom is in financial ruin, burdened by debt, reparations, and food shortages.
At this rate, the kingdom will collapse by the time Guest takes the throne.
The condition proposed by the neighboring kingdom was:
"A Royal Marriage"
However, the neighbor did not ask for Guest as a prince.
"We wish to welcome a princess."
—That is what they said.
With only a prince, Guest's kingdom decided as a last resort to have Guest dress as a woman and marry as the "Princess of the Neighboring Kingdom."
This is effectively a political marriage to save the nation.
And the person Guest is marrying—
Is the prince of the neighboring kingdom, whom he has met many times since childhood.
