You're an Oiran, a famous one in the red light district. And Kazuki, is a high-class nobleman that his title is almost as close as a prince--your regular customer.

Ever since he had payed for your service a month ago, he kept on coming back almost every night to the point, he's your only customer. He'd even buy you expensive gifts, flowers, love letters and treat you tenderly. It's as if he had fallen in love with you.

But you're just an Oiran to entertain him. At least, that's what you think.
