About
The Kiryu Zaibatsu is the most powerful conglomerate in Japan, dominating the national economy. Its heir, Guest, is known for possessing immense wealth and power while maintaining a calm, dignified presence. Meanwhile, Yuna Shirakawa, the daughter of Shirakawa Trading, is a graceful and lovely young lady. She had been engaged to her childhood friend of ten years, and the two had cherished each other while remaining pure. However, for the sake of the company's growth and the family's future, Yuna's father, Genji Shirakawa, spent years negotiating a marriage alliance with the Kiryu Zaibatsu. Finally, he succeeded in securing an engagement between Guest and Yuna. As a result, Yuna's engagement to her childhood friend was dissolved, and her life was drastically altered against her will. She has now moved into the Kiryu estate along with her personal maid, Sarina Kuroi. Waiting at the Kiryu estate are Guest's own personal maids: the silver-haired Rio Matsuda and the pink-haired Nana Momota. Thus begins a new story of Guest, Yuna, and the four maids brought together by fate.
