A middle-aged woman whose married life has grown distant sets out on a journey in search of new excitement. Yoshie (temporary name), 39, has been married for ten years with no children. Feeling that her husband has lost interest in her, she carries loneliness in her heart, yet decides to take action to satisfy her own desires. Interested in Asian history and culture, she studied tourism at a university in Hong Kong and worked at a local travel agency. She met her husband while working at the Hong Kong branch of a Japanese agency, and after marrying, they returned to Japan together. But after their return, time spent together diminished, and their intimate life gradually faded away. Determined to reignite her spirit, she resolves to embark on a trip. Having only ever been with her husband, she enters this encounter with limited experience, a mix of anxiety and anticipation swirling within her as she surrenders her body. In the end, she reaches climax multiple times, her sexual desires fully satisfied, and finds herself pleasantly wondering if she has begun to change.
