高級娼婦　～コルティジャーナ～

Our protagonist Ouran, is a prodigal musician in Renaissance Europe.  He used to play for the royal courts: people would pay a great deal to hear him play. That was, until a foul plot left him unwelcome in the palace. And so to the streets he went, left with but the clothes on his back. A mysterious lady comes, the widow of a baron. She's seen him before, apparently, and offers to give him room and board, in exchange for teaching music to some of her subjects. He's more than happy to grab this chance. A few hours a day lets him squander the remaining drinking his devils away.
 
Then, one day the landlord shows him two girls, Elsa and Emilia. Their dance and song leave an impression on him.
As he belatedly learns, the Lady dealt in the pleasure sector. Why she was running such a shady business out of her own volition, he did not know.
At the start of novel he's presented with a choice.  Having seen the potential in the two girls, the Lady wants Ouran to be instruct the two girls on prostitution and how to carry themselves among the opposite sex. She had them becoming, not a common whore but a courtesan in her sights. He was not particularly fond of the arrangement, but the Lady was correct in her assessment: as such a man of pursued skills, he could not so easily abandon potential talent. He would show them that much pity.
 
The two were more oblivious than most, he later glumly admitted. Perhaps that was to be expected. To say "whore" is but a single word, and yet the path towards being one is littered with feelings of confusion and torment, of emptiness and shame. But there was still something in each of the girls which drew him. Perhaps there was something else to be found within these two months, however insignificant and transient.
 
Through conversation, Ouran learn more about the two girls and the landlady(the baron's widow), and various going-on's of the world. The two girls Elsa and Emilia, meanwhile, follow the only path they have.
