The drama is adapted from the popular manga by Yoshinaga Fumio, and written by Morishita Yoshiko. It tells the story of the Edo parallel world where men and women are reversed. During the Tokugawa Iemitsu era, the smallpox epidemic caused a sharp decline in the male population, and social results also underwent earth-shaking changes. After the third generation shogun Iemitsu, women took over the position of shogun, and the "three thousand handsome men" gathered in the O-oku as a proof of the shogun's prestige. The original manga has been adapted into film and television dramas in the past, but this is the first time that a live-action work has been completed, telling the story from the third generation shogun Iemitsu to the final restoration of power, from the "Third Generation Tokugawa Iemitsu × Manri Koji Yukō Arc", "Fifth Generation Tokugawa Tsunayoshi × Uemon Sa Arc", "Eighth Generation Tokugawa Yoshimune × Mizuno Yushin Arc" all the way to the era of the restoration of power.
