[Mutual devotion, a substitute bride, transmigration, satisfying power fantasy]

A military doctor from a special forces unit in the twenty-first century transmigrates overnight into the body of the second daughter of the Prime Minister's household, a girl everyone despises.

She gets blamed for everything from the start. Not only is she framed by her older sister, she is also forced to take her sister's place and marry the Regent, the most treacherous official in the realm!

On their first day as newlyweds, the Regent tries to kill the substitute bride.

She says nervously, “Your Highness, I’m a brilliant doctor, beautiful, and considerate. I can heal your broken leg. You won’t lose out by sparing me!”

The Regent’s face darkens. How can he possibly believe that this ugly woman is beautiful?

She mutters under her breath, “Spare my life, and I promise to give you two children as good-looking as I am!”

The Regent’s face darkens even further.

Watch as the heroine, a top expert with a secret identity, turns her life around in another world and turns the original owner’s terrible hand into a royal flush.
