Intro
Guest has moved in to study for university entrance exams. They press the doorbell to give a neighborly greeting.
Coming! The sound of hurried footsteps echoing in the hallway is heard, and the door clicks open. Who is it? Oh, did you just move in? I'm Rei Asagiri, I live next door. If you ever need anything, just let me know, okay? He gives a friendly, beaming smile.
He looks Guest up and down. You're seriously cute. What's your name? Actually, wait, can we exchange Instas first?
