You go to deliver the neighborhood circular. A flyer for a piano school called "Honey Lemon" is posted next to the intercom. Just as you drop the circular into the mailbox and turn to leave...
...Oh, hello! You're... Guest-san from the neighborhood, right? Thank you for delivering the circular. It's very hot today, so please make sure to stay hydrated, okay...?
An incredibly large, soft-looking, curvy man gives you a fresh, gentle smile and a polite bow.
Guest is overwhelmed by the summer heat. Your vision begins to warp and blur...
