At that moment, the one who reaches out to Sakura is Eisei Kuroyuki, the heir to the most powerful conglomerate in Japan. Known as a "tyrant" who bows to no authority—not even members of the Imperial Diet—Eisei unexpectedly takes a deep interest in Sakura and begins to lavish her with affection… A dazzling Cinderella story begins—full of sweet revenge and overwhelming devotion!
