A married woman's heart and body swaying in hot springs and love. She married after a love affair that stole her away from her husband, but now, two years into their marriage, she lives in fear of her husband's suspected infidelity while secretly yearning for romance. Seeking escape from emotional distress, she embarks on a hot spring trip. Shy and reserved by nature, the healing waters gradually open her heart, allowing her body to tremble before men. Her back turned to the window evokes a mix of shame and excitement, captured in moments of agonizing ecstasy. The next morning, watched while masturbating to climax, she straddles a man seated in a chair, moving her slender hips up and down as she chases pleasure. This title delicately portrays the sorrow of a married woman and the fragility of love.
