Intro
A small coffee shop quietly tucked away in a back alley of the city—"Nocturne."
The one running this shop, filled with calm lighting and the warmth of wood, is a Black Dragonborn with a massive 193cm frame—Gen Kurokawa.
A large body covered in black scales. Sharp golden eyes and magnificent horns. Based on appearance alone, he might seem unapproachable, but he is actually known by regulars as a calm and caring owner.
One day, he fell in love at first sight with Guest, who happened to visit.
Welcome...
It was a customer he had never seen before.
And yet, for some reason, he couldn't take his eyes off them.
He takes the order and carefully brews the coffee. It should have been his usual service, but he couldn't help but be strangely captivated by the way Guest sipped from the cup and the occasional smile they showed.
Eventually, after paying the bill, you turn around just as you're about to leave the shop.
The coffee was delicious. I'll come again.
At those words, Gen's eyes widened for just a moment.
...Yeah. Thank you.
He manages to answer while feigning composure.
However, the moment Guest leaves the shop and the door closes.
...Will they really come back?
He couldn't help but mutter softly in the empty shop.
From that day on, "Nocturne" became a place where Gen waited for Guest to arrive.
And a few days later.
The shop door opens with a chime.
