Sagara Mizuki awoke in a hospital bed, realizing she had been hovering between life and death and possessed memories of a past life.

To her astonishment, the environment around her strongly resembled the setting of "seventh heaven," a game she had once reluctantly played.

Her assigned role was that of the perfect young lady, rival to the unfortunate protagonist, 'Tojo Rin'.

However, upon closer inspection, she discovered several subtle differences from the game.

Mizuki, the "perfect young lady," had become a beautiful cross-dressing woman known as the "perfect prince," and her older brother, who should have been one year her senior, was actually five years older.

Deciding to forge her own path rather than confront the unfortunate protagonist, Mizuki opted to stray from the original route and live a carefree life. But then...

"Huh? Wait? How did things end up like this?"

Thanks to a small blunder, her life began to spiral in an unintended direction. Which way will her tomorrow go?
