30-year-old Sayaka belongs to the so-called "arasa" generation. Unmarried, she spends her days in love hotels located in Shinjuku's bustling district. Diligent at work and currently in a relationship, she remains completely indifferent toward marriage. For her, daily life consists of an endless series of unfulfilling, empty moments. The reason she started working at a love hotel stemmed from a surprisingly similar motivation: a friend once mentioned how "perverted couples wanted others to watch their sex," sparking her curiosity to try it at least once. Having always harbored sexual curiosity, this became one of her driving factors. However, after actually starting the job, she rarely encountered such situations. Even after two years, she remains someone who simply can't tolerate boredom. Since childhood, she's craved stimulation, feeling anxious whenever her schedule has gaps. Even on days off, she forces herself to stay busy. In this way, she's fallen into what's known as "blank anxiety syndrome"—a psychological condition where, on days without work, she constantly worries: "Am I being lazy?" or "Is everything going to be okay?" This reflects an unconscious anxiety commonly found in overly conscientious individuals.
