Amidst a severe decline in birth rates, Japan has introduced a new legal system requiring newly married couples to stay in a "procreation-only shelter" on their wedding night. This facility, commonly known as "Honeymoon," is filled with special hormones that directly stimulate human erogenous responses. Within this intense environment, the couple's shyness and nervousness—especially during their first intimate encounter—intensify the erotic atmosphere. This phenomenon has drawn significant social attention as a new cultural trend.
