Yuuna Serizawa, 31 years old. She married her husband, a lawyer, with whom she had been in a relationship since her school days, and currently leads a busy life as a career woman at a securities company. However, both husband and wife are overwhelmed by their demanding jobs, resulting in an extremely limited sex life since marriage. Mrs. Serizawa herself had been struggling emotionally, saying, "Back in my 20s, I was fully focused on work and enjoyed it, but now that I'm in my 30s, I want to have children and I keep wondering—am I really okay as a woman like this?" This inner turmoil reaches its breaking point, captured on camera as she releases her pent-up frustration and sexual desires. Her honest confessions and the gradual liberation of her body—worn down by the emotional distance in her daily life—create a deeply compelling and captivating experience for viewers.
