婚約破棄しろと言われたので悪役令嬢を演じてみたいと思います

Synopsis

Mia grew up a commoner, but after her parents died, she and her younger brother were taken in by their uncle, an earl, and spent their days as a countess. One day, however, Mia is chosen as the bride-to-be of the crown prince Albert, which brings her mother-in-law and sister-in-law Isabelle into disrepute. Furthermore, Isabelle orders Mia to play the role of a villainess and intentionally break off the engagement...? This is the start of a love fantasy between the dauphin and a (pretending) villainess who are not always straightforward!
