The Men of Yoshiwara: Kikuya

At this red-light district, a certain young lady buys a night with a man who won't become anybody's. Because she wanted to have a child. Because she desired love. On this island, young men aren't birthed. Consequently, all the women go to Yoshiwara. There wasn't a single day she thought of this as abnormal or strange. However, one day... She decided to venture to "Yoshiwara", a nightless city that emits a dazzling light without pause. For the first time ever in her entire life, she viewed the procession of the beautiful male courtesans. The protagonist, Hidetomi Misawo, becomes captivated by Yoshiwara and its men. "How about it? Why don't we spend the night together?" Misawo decided to step foot into Yoshiwara's highest-class pleasure house, "Kikuya"... [Translation of Otoko Yuukaku's official website story summary.]
