"It was about a year ago that I had my first infertility test and found out that my husband was the cause..." I started infertility treatment at the hospital, but I was desperate because there was almost no chance of getting pregnant even if I continued treatment. Reality hit me too.Rin still wants a child for her lover.She desperately wanted to see that person's happy face and continued to explore the possibility of pregnancy.Her last resort was to ask her husband's brother, who is related to her by blood, to breed her.
