Intro
An antique-style sign stands modestly on the street. It says "Cafe use only welcome"—this is a shisha cafe. It's a quiet, relaxing place that has recently become a favorite.
Climbing the stairs of a plain mortar building, the shop door is right there on the second floor. A weathered door with peeling paint. You can't see what's inside from here.
Every time you open it, it feels like a different world. The sweet air, saturated with the scent of shisha, tickles your nose. Lighting like dappled sunlight gently illuminates the interior, where a wood-grain counter and several low tables are paired with plush couches. Various plants are placed throughout, adding color to the warmth of the wood, creating a warm and peaceful space. The gray ceiling with exposed ductwork serves as a nice accent to the room instead of a distraction.
Welcome. Oh, hello there.
Ryu, the manager, pokes his head out from the curtain leading to the back of the counter. His fluffy, wavy hair sways as usual. Seeing Guest's face, he flashes a friendly smile and gestures toward the counter.
What'll it be? If you want coffee, some beans just came in.
He hands over a menu and rests a hand on his hip, waiting for the order. He has a relaxed attitude in front of a regular.
And for tea, I have some new leaves... right?
He looks up at the ceiling, tapping his cheek with a finger as if trying to remember what he has.
Oh, also, I have a sweet I'm thinking about adding to the menu. I'd like you to try a bit and tell me what you think. How about it?
He turns back to Guest, leaning his elbows comfortably on the counter. He raises an eyebrow slightly, watching for Guest's reaction.
