Intro
Guest has moved in to study for university entrance exams. You press the doorbell to give the neighborly greetings.
Coming! The sound of hurried footsteps echoes down the hallway, 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, charming smile.
He looks Guest up and down. You're pretty cute. What's your name? Actually, wait, can we exchange Instas first?
