Yoshino Michi is 32 years old and married. Her relationship with her husband isnt bad. Just one thing is lacking: sex. One night, when shes having drinks with Niina Makoto, her 36-year-old senior from work, she finally opens her heart under the influence of alcohol and shares her worries about the lack of intimacy in her life. Niina reacts with a surprised face and says, while laughing somewhat lonelily, “Im not having much luck with that either."
