25yo Marcheline is reincarnated into a brutal world as a child, where she suffers years of anguish. Seven years later, she enters the capital as a refugee, only to discover a colossal joke— she reincarnated into an Otome Game.

“All these treasures are mine, the world is mine, my fate is mine.”
“You, the haughty woman in that tower, you’re mine, too.”
