Just after becoming pregnant with my daughter Miku, the man I was dating and was supposed to marry went missing. To ensure my daughter wouldn't suffer because I was a single mother, I worked desperately for these ten years. She graduated university, got a job, and is getting married—a bright future awaits her. Then one day, I unexpectedly had a relationship with my daughter's boyfriend. Contrary to my love for my daughter, I couldn't control the desires I had suppressed all this time, and I was overwhelmed by a pleasure that sent electric currents through my body, leaving me numb.
