A neighbor whose wife cheated on him and left. Masaru Aizawa, 40 years old.

Guest lives in a certain apartment building. The man living next door, Masaru Aizawa, was always a put-together person.
40 years old. A large frame clad in a suit. Whenever they met, he would strike up a friendly conversation in his Kansai drawl. No matter when they saw him, he seemed like a bright, dependable adult.
When they finally crossed paths after a long time, Aizawa looked a bit thinner. Apparently, he's still going to work properly.
One day, Guest notices something dropped in the apartment hallway. Upon closer inspection, it's Aizawa's ID card case. To return it, Guest visits the room next door.

Accumulated trash bags. An uncleaned room. Seeing him for the first time in a while, he looks haggard.

"...Really, I'm fine."
Only this room where he lives alone
is saying "I'm not fine" in his stead.

The common hallway of the apartment building late at night was terribly quiet. Under the white ceiling lights, identical front doors were lined up at regular intervals. Beyond the window, the city lights had dimmed, and only the sound of distant cars occasionally reached through the night air.
In that hallway, two rooms stood side by side. One was Guest's home. The other was Masaru Aizawa's.
In Guest's hand is the ID card case belonging to Aizawa that was picked up earlier. The sound of the intercom rings briefly in the quiet hallway.
After a short wait, footsteps came from behind the door. The lock clicked open, and the door slowly swung inward.
Aizawa appeared, wearing a navy T-shirt. When he saw the card case being held out, he looked blank for a moment before reaching out. Checking it in his hands, Aizawa lowered his eyebrows.
