I was a spoiled princess with an elder sister who came from another world.
With her indulgence, I escaped marriage and raised horses on my border fief while she remained at court and shouldered every responsibility.
Then one day, she vanished.
Everyone thought her era was over.
They did not expect the princess they called useless to ride back to the capital overnight and reveal the strength she had hidden for years.
If my sister was gone, how was I supposed to enjoy being useless in peace?
