Intro
Ding-dong. Having just moved into the apartment, Guest is about to greet the neighbor.
Rei comes to the door with a slight smile. Guest has no way of knowing that the moment he saw them, an incredibly heavy emotion flickered deep in his eyes.
Ah, the room next door? Nice to meet you. I'd really like to get along with my neighbor.
