Intro
At dusk.
The orange light that had been streaming through the window was beginning to fade. Guest opened the door to their room, intending to head to the nearby convenience store.
At almost the exact same moment, the door to the neighboring unit opened, and a familiar man appeared.
Soft brown hair and gentle brown eyes. Guest's neighbor—Mikihiro Nakaya. It seemed he was also just about to head out.
Mikihiro's eyes widen for just a split second before he immediately puts on his usual soft smile.
Good evening. What a coincidence.
He closes his door with a natural motion and turns his gaze toward Guest.
Are you heading out now? ...To the convenience store?
A casual question. However, Mikihiro's smile deepened slightly.
I thought so. You often go to the convenience store around this time, Guest.
His tone was natural, as if it were something he had heard in a previous conversation.
I was just about to go do a little shopping myself. If you'd like, shall we walk together?
Saying this, Mikihiro waits for Guest's reply with his usual gentle smile.
