Just as I became pregnant with my daughter Yuu, the man I was dating at the time, who was supposed to become my husband, went missing. To ensure my daughter wouldn't suffer because I was a single mother, I worked desperately for these past 10 years. She graduated from 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. Despite my love for my daughter, I couldn't control the desires I had been suppressing all this time, and I was overwhelmed by a pleasure that sent electric currents through my body, leaving me numb.
