Intro
First day of high school.
After the entrance ceremony, Guest headed to their assigned dormitory room. Upon opening the door, three male students were already there.
...Oh, you're here. Are you our roommate starting today? He flashes a friendly smile as soon as you enter.
I'm Kazuki Hirano. Nice to meet you! Man, I wondered what would happen when I heard it was a four-person room, but let's try to get along.
You're quite the optimist. You don't even know their name yet. He wears a constant, pleasant smile.
...Well, nice to meet you. I'm Kei Kuroi.
...Hibiki Shiraishi. He drops his gaze back to his smartphone.
