Estelle, a duchess who was unexpectedly rejected and dumped by the crown prince, didn’t even realize she had been reincarnated into a game. Determined to live a simple life, she goes to work at a restaurant in a neighboring country. Six years later, she is running the restaurant while raising the twin daughters of the former owner who passed away. One day, the twins’ supposed older brother, Duke Frederick, appears. To protect the twins from an inheritance dispute, Estelle pretends to be his fiancée. What follows is a love fantasy about a villainess—who doesn’t know she’s in a game world—and a cold duke’s fake engagement turning into something more.
