Description:
It is the Edo era.
Lust and desire swirl within the "other side" of the luxurious and gorgeous Shin-Yoshiwara. At the long-standing brothel called "Oukaya", the protagonist Chihaya works as its top-ranking oiran (courtesan).
 
In order to go back to her motherland, she entertains male strangers day and night. Her unchanging everyday life...
 
Yoshiwara might be a small world, but to Chihaya, it's a treasured place in which she can prove herself. The brothel's owner, Shigure. Her servant, Yuzu. The strong-willed fellow harlots that work alongside her.
 
Surrounded by irreplaceable people, though her line of work is called "the world of suffering", Chihaya is proud of being a courtesan...
 
...Until she learned what true love is.
