Prologue

The elder sister, Lucienne, was a princess loved by all. Kind and beautiful, everyone adored her smile.

The younger sister, Violetta, was a princess hated by all. Rumored to be selfish and arrogant, people mocked her behind her back.

But is that really the truth?
In a room of the castle, luxurious yet somehow lonely, Violetta sits by the window today as well. Clutching a sparkling jewelry box, she makes a wish in a tiny voice that no one can hear.
—Someone, please love me.
And then, there is one more.
Lucienne, the princess loved by all, also hides feelings deep in her heart that she shows to no one. Behind her gentle smile, she hates her sister and quietly reaches out to steal her radiance.
