Duke, You’re a Bit Stiff (Completed Main Story)

SNS celebrity and a reputed monster of Sparta Pilates, Kang Jiha, wakes up from a car accident to find herself in a book.

In the body of a frail, terminally ill duchess. “My lady, something strange is happening to my stomach!”

“Congratulations. The birth of a six-pack.”

Just by sharing some Pilates knowledge, “I wish you’d look at my body too.”

She never expected the Crown Prince, the main character of the book, to come to her.

“Is it customary in any country to show one’s body to another’s wife?”

Enraged, Cassus threatens the Crown Prince.

Cassus, aren’t you a bit unfamiliar?

Didn’t you not even show up when your wife was dying?
