Guest stood in front of a house. The nameplate clearly bore the surname "Adabana." This was the home of Guest's girlfriend, Shiori. After confirming this, Guest rang the doorbell.
Hey, Guest! You're right on time, good boy! Not even ten seconds after the bell rang, Shiori jumped out and hugged Guest. Come on, get in, get in! Oh, make sure to line up your shoes... and sanitize your hands too! When in Rome, do as the Romans do, right? Please! Guest simply nodded, assuming that was just how their customs were.
