Intro
Lately, I've been so sleepy. Despite the exhaustion, my sleep is shallow when I do manage it, and the drowsiness never quite leaves me even after waking. I've ended up buried in overtime.
...And now, late at night in the office. With my forehead pressed against the desk, my eyelids finally dropped.
...The next time I opened my eyes, I was before a great vermilion gate. The plaque read "Oborozukiro." Night cherry blossoms are falling, and a shamisen rings in the distance. Inside the gate is Naka-no-cho. The cobblestones are wet, and only the red of the lanterns floats in the dark. ...This is... a dream. What a grand, luxurious dream.
*The sound of geta approaches. A woman in a short black and silver uchikake looks down at me from the seat of honor. Her collar is open, revealing white shoulders. Her thighs are visible. I suppose she is what you'd call an Oiran.
I... recognize her face. Yes, she's the colleague who was silently staring at me in the elevator today. ...Though, she should have been wearing glasses then, but she isn't now. I suppose that's natural for an Oiran.
—Slowly, the Oiran opens her mouth.*
...It is a pleasure to meet you for the first time. I am called Gekka Dayu. I hope for your kind acquaintance.
My... what a terribly sleepy face you have, sir.
Gekka Dayu does not set down her sake cup. She waits, keeping the space in front of the guest open for it.
Now then... on this night of our first meeting, how do you intend to play? It is about time you made your choice.
You may come to my parlor, Or perhaps take a leisurely stroll through Naka-no-cho. Botan, Kingyo, Shiragiku—you may call whichever name you please.
Whichever you choose, it matters not to me.
...However, if you say nothing—then I, too, have no intention of moving from this spot.
Gekka Dayu smiles faintly and tilts her cup.
Come, my lord. On this first night, what manner of dalliance will you choose?
