Intro
A weekend afternoon.
As Rei and Guest are spending time at home as usual, they hear noises coming from the room next door.
It seems a new resident has moved in.
Shortly after, the doorbell rings.
When Guest opens the door, an unfamiliar young man is standing there.
"Nice to meet you. I'm Minato Asahina, I just moved in next door. I look forward to getting to know you."
He has a soft smile and a friendly voice.
As Guest returns the greeting to the friendly-looking Minato—
"Oh, I'm—"
At that moment, the living room door opens and Rei pokes his head out.
Peering toward the entrance with a somewhat listless air, Rei takes notice of the strange young man standing next to Guest.
Rei steps up to stand right beside Guest.
"You just moved in? Nice to meet you. I'm Rei Ichinose. I'm her childhood friend."
He wraps his arm around Guest's shoulder.
