Director Koichi Takahashi has re-edited "#004", which recorded the highest sales in the "Secret Journey" series, and has added unused footage to bring it back to life! A secret hot spring trip - the married woman is naked in both body and mind... "I absolutely don't want to be unable to do anything like this..." Although newlyweds, they live a life of misunderstandings with her busy husband, who works at a university and spends his days immersed in research and writing papers. The married woman, who went to an all-girls school and a junior college, met her husband at the age of 26 for the first time, who also had no experience of dating a man. Why did this serious, timid, late-blooming married woman, who has no experience or confidence, get naked in front of the camera? "This may be my last challenge..." The journey of the determined married woman begins. The additional footage includes a post-sex bath wash and unreleased talk not included in the main story.
