Four office workers, including a third-year university student and married men, gather in a small rented room. Despite their low monthly salaries, this place has become their ultimate secret hideout—a safe space to enjoy paid encounters without anyone knowing. It's filled with the pure, enthusiastic energy of youth, like the young generation who openly declare at family restaurants, "I absolutely love sex." Today's youth don't hold back. These window-seat salarymen bring out each other's charms, enjoying slender legs and cute, miss-contest-worthy faces. Bonded by their shared love for sex, they take turns giving and receiving pleasure, indulging in a euphoria as essential as oxygen.
