A Japanese woman put her baby up for adoption after finding out that the father of her second child lied about his identity.
According to the Japanese news outlet Tokyo Shinbun, the woman - who is in her 30s - is suing him for $2.86m (330m yen).
She believed that she had found a well-off Japanese man who had an education at the Kyoto University, and slept with him on 10 occasions to conceive the child.
The woman had already had one child with her present husband, but after learning that he had a hereditary disorder that could be passed down to his children, she chose to try for a second child with a donor.
She turned to social media for aid in finding the ideal individual.
And in July 2019, their efforts were rewarded.
However, soon after becoming pregnant by the donor, the woman, who is unidentified in reports, realized that the biological father of her unborn child was a married Chinese man who did not attend the elite research university.
