Lady Emilia Paulette possessed everything: beauty, intelligence, and every other virtue.

On her fourteenth birthday, through a plot by her elder sister Delia, who detested her, their bodies were swapped.

The beautiful younger sister, now trapped in her ugly sister's body, was expected to be heartbroken by her predicament... but she wasn't.

"After all, being exceptionally beautiful or engaged to the Crown Prince isn't a good thing at all."

Having gained her freedom, she nonchalantly revels in her second life, using her sister's body.

This is a story about her unexpectedly finding happiness as she does so.

※ The bodies of the younger and elder sister remain swapped and will not return to normal.
