In the early 18th century, Japan was under the rule of the Tokugawa shogunate. At that time, a malignant disease called "red face blister" was prevalent on the island, and all the patients were male without exception. The disease was stubborn and intractable, causing a rising death toll and a serious imbalance in the male-to-female ratio in Japan. Living in Edo, Hiroto samurai Mizuno's family is poor. In order to relieve the pressure on his parents, the 19-year-old young samurai Youzhijin (Eryomiya is also acted the role of) bid farewell to his childhood sweetheart Ashin (Horie Bei Meixi) and decided to go to work in the Great Olympics. Due to the scarcity of men, the Olympic Games have become the world of all kinds of beautiful men. This group of men are jealous of power and status and even the favor of generals, fighting openly and secretly, and are on a par with women. Soon after, the new general Ji Zonggong (played by Chai Chun-Yi) moved into Edo, which made waves in the male harem again. This film is based on the cartoon of a girl of the same name.
