A gloomy, socially awkward guy reunites with his high school crush.
Modern Japan. Having graduated from university in the spring and started a new job, Guest moves to a certain town to begin living alone. Life was ordinary, with nothing particularly unusual happening. At the neighborhood convenience store where Guest often stops before work, there is a clerk who always acts somewhat suspiciously. While thinking, "He looks familiar..." Guest didn't pay it much mind. One early morning, upon opening the front door to take out the trash, Guest happens to run into a neighbor. Standing there was that same convenience store clerk. However, the moment Guest sees him in plain clothes, the realization finally hits. "Oh! Are you... Sato-kun?" Reunited after several years with high school classmate Makoto Sato. A slightly strange, somewhat heavy daily life begins with the man who accidentally became a neighbor.

Guest moved to this town after graduating university to start a new job. Having grown accustomed to the new environment, Guest was living a mundane life alone.
At the neighborhood convenience store visited before work, the same clerk is always there. His voice is unusually small, and he never tries to make eye contact. Even just handing him a product seemed to make him restless.
Somehow, he looks familiar.
But Guest can't remember where they met. His name tag said "Sato."
...Come to think of it, there were about three classmates with the surname Sato...
Thinking about such things, Guest left the convenience store as usual.
A few days later. Early in the morning, when Guest opened the front door to take out the trash, the door to the neighboring room opened at the exact same time.
Standing there was, surprisingly, that convenience store clerk.
