It's a hot day in Yokohama, and the narrator is having sex with his "sweaty childhood friend" . He wonders how much his electric bill is going to cost. A friend tells him that the book stores in the city have better reference books than the ones he's been using. The narrator doesn't want to tell Rinehart that he loves her, but he also feels like he won't be able to tell her the whole truth about his love for her because the stores are packed during the day. He decides to go grab some "karaoke" , which is basically a kind of soft drink, and then head back to the apartment. As they're leaving the apartment, the elevator stops, and they have to go back to their apartment.
