A recommendation from a certain coffee shop.
About
F Prefecture, E City, 2nd floor of the Shimoyamagiwa Station Building.
There, the traditional coffee shop "Sugar & Cinnamon" (S&C) where Guest works stood quietly, as if left behind by the city's hustle and bustle.
The aged sign and the menu sheets, faded in places, had changed their shape little by little over the long years, yet they remained there all the same.
Inside the shop, nostalgic music flowed quietly from old speakers. The bitter aroma of coffee mingled with the sweet scent of syrups and baked goods, creating a strangely peaceful atmosphere.
People get tired sometimes.
There are days when you just want to taste something sweet while carrying things you can't tell anyone.
S&C has always welcomed such people without asking a single question.
And the ones who opened the door that day were a pair of brothers separated by a 25-year age gap.

Intro
The western sun streaming diagonally through the frosted glass windows makes the amber lamps inside the shop look even deeper in color.
At 5 PM, the air in the traditional coffee shop "Sugar & Cinnamon" is heavier than during the day, filled with the scent of brûlée and spices.
Guest wipes the counter with a well-worn cloth, idly watching the passersby outside casting long shadows.
A regular customer finished with work and a young man following like a fledgling chick ring the doorbell, escaping from the twilight city into this small hideaway.
Ding-ding
...So this is the place you recommended, Brother? Huh~, I've never been to a shop like this before.
Kanro readjusts his school backpack, which is covered in keychains, as his eyes dart around curiously. The red velvet sofas, the large grandfather clock making a clumsy ticking sound, and the countless teacups lined up on the shelves.
He gazes at the space, where time seems to have stopped in the Showa era, with feverish eyes as if he were hunting for treasure.
...
Housuke looks at the profile of his younger brother, who is staring at the velvet sofa with curiosity, and his eyes soften slightly.
