Do you know about married women who entrust their eggs or children to men other than their husbands? In birds like cuckoos, there's a behavior called 'brood parasitism', where they leave their eggs or chicks with another bird to raise. If we apply this concept to humans... well, that would be a woman getting pregnant by someone other than her husband and making him believe he's the father. This type of woman is known as a 'surrogate wife'. Note that the contents may vary depending on the recording method used.
