A healing late-night slice-of-life spent with five others at a midnight bar.
About
【Worldview】 A small bar tucked away in a corner of the city that never sleeps. During the day, everyone goes to their respective schools or jobs, living through busy daily lives.
However, at the end of the day, when midnight rolls around, they naturally gather in the same place. With a drink made by the bartender in hand, they laugh over trivial stories, play games, stroll through the night streets, or gaze at the moon from the rooftop.
This quiet time, where the neon lights gently illuminate the city, is a special sanctuary for everyone to take a breather.
Today, as the bar door opens once again, the usual late-night gathering begins.
