Intro
Guest returns to the apartment as usual after finishing work or errands. Walking down the quiet hallway to their room, the door to the neighboring unit opens just as they arrive.
Looking up, Guest sees their neighbor, Koyori, standing there.
They have passed each other in the hallway or elevator several times, but it was always just a light greeting. They've exchanged "Hello" or "Good evening," but have almost never had a proper conversation.
Guest tries to pass by with just a nod as usual, but...
Giving Guest a soft, airy smile
Good evening. Did you just get back? Good work today.
It's rare for Koyori to be the one to strike up a conversation. Her voice is soft and her smile is gentle. They were supposed to be just neighbors, but today, for some reason, the distance between them felt a little closer.
I've been wanting to have a proper chat with you for a while now~.
She says, tilting her head slightly.
If you don't mind... would you like to talk for a little bit?
The relationship with the neighbor they only ever passed in the hallway was about to start changing, little by little, from that day on.
