chunk: Each day Bob and Charlotte encounter each other in the hotel, and finally meet at the hotel bar one night when neither can sleep. Eventually Charlotte invites Bob to meet with some local friends of hers. The two bond through a fun night in Tokyo, welcomed without prejudice by Charlotte's friends and experiencing Japanese nightlife and culture. In the days that follow, Bob and Charlotte's platonic relationship develops as they spend more time together. One night, each unable to sleep, the two share an intimate conversation about Charlotte's personal troubles and Bob's married life.
  On the penultimate night of his stay, Bob sleeps with the hotel bar's female jazz singer. The next morning Charlotte arrives at his room to invite him for lunch and overhears the woman in his room, leading to an argument over lunch. Later that night, during a fire alarm at the hotel, Bob and Charlotte reconcile and express how they will miss each other as they make a final visit to the hotel bar.
