This one is so cringe but I tried to make him as canon..
They call you Meido and you are an orphan, taken in by the headmistress of the Kyogoku House. You grow around Oirans and clean after them, and you make a good impression on Warabihime aka Daki, and especially her hidden brother.
You were humming as you rubbed the sheets in soapy water. You were a humble worker at the Kyogoku House, a high-class brothel in Tokyo. While it was a brother and full of high-class Oirans, you weren't one of the women blessed with beauty as they were.
Since you couldn't work as an Oiran, you were trusted to prepare the meals for the gorgeous women and to clean after them and their clients.
It wasn't that you were horrendously ugly, but you did have a scar over your right eye and according to the headmistress Omitsu, your talents were best put on when doing physical labor such as cooking or cleaning, not entertaining men.
You weren't born with the scar, but according to the headmistress, your mother had tried to kill you when you were just an infant and so you had been left on Kyogoku House's doorstep. You had been lucky and the accident hadn't taken your eye and you were still able to see with it.
Mistress often told you that she wasn't running an orphanage, so she made you work since you were small. It's all you knew. While you were a cute kid and many Oirans treated you well, there was this one woman who you admired most.
She was gorgeous as she was cruel, and she was by far the most beautiful woman you ever worked for. You learned soon at a very young age that if you wanted to make it, you needed to be on good terms with the gorgeous Oiran.
It wasn't easy, but you had no other life outside the house so you focused on pleasing everyone. Then, one day the Oiran brought you a set of extremely bloody sheets and threw them at you.
"Clean this and don't ask any stupid questions! Am I clear!?" She snapped as she turned to leave and you were left with a huge mess to clean... But it was a request from her so you tried your best to please her!
So, the next night you went to take her sheets back and you were putting them on when her voice rang behind you.
"You actually got the blood off." The gorgeous woman stated as she inspected the snow-white sheets, "You might just be useful."
That night you had made a good impression on her... And to the person hiding within her as well.
Slowly, years passed and you grew up into a fine young woman. Not maybe the prettiest, but a hardworking and diligent young woman. And so, you were washing sheets again when you heard you being called with your nickname.
"Oi! Meido!"
You turned and saw the headmistress glaring down at you.
"Yes, Mistress?" You asked and the woman pointed at the house, "Warabihime wants to see you!"
The most gorgeous Oiran you had the honor of serving?
"But the sheets-?"
"One of the girls will finish them! Now leave!"
"Alright, Mistress," You nodded, leaving the sheets on the water and heading inside. You knew the Kyogoku House like the back of your hand and way to the prettiest Oiran's private room. As you stopped by the room's entrance, you made sure to knock and wait for permission to enter.
"Who is it now!?" Came the woman's voice and you replied, "It's Meido. I heard you wanted to see me?"
"Come in!"
And you did, making sure to close the door behind you. The room was dimly lit and the Oiran, Warabihime herself was admiring her appearance from the huge mirror.
