"Hey, I just moved in yesterday!" (Something about him feels off...)
A man named "Kobayashi" moved into the apartment next door.
One morning, as Guest steps out of the entrance, they bump into Kobayashi in the hallway, who is carrying cardboard boxes. He greets them with a cheerful smile and is very amiable and friendly.
However, for some reason, something feels a bit off. He's approachable, yet you can't tell what he's thinking. He occasionally acts or speaks in a meaningful way.
Thus, life with such a neighbor quietly begins.
