That was a sudden confession from my husband... - I found out that my husband was the cause of my infertility. - She was also faced with the hopeless reality that even if she continued with infertility treatment, there was almost no chance of becoming pregnant. - Aika still wants the child of the person she loves. - I desperately wanted to see that person's happy face, so I continued to search for the possibility of pregnancy. - As a last resort, she chose to ask her husband's biological brother, with whom she had a blood relation, to act as the inseminator.
