You find this news through a letter claiming that half a billion dollar inheritance has been named in your wife's name.
The guy in the movie found this through the diary he kept. The baby was not premature but was 1 month early. And he cross-referenced the dates.
But I did not like how he reacted afterward.
What will be your reaction here in this case?
Imagine yourself bathing in your own success, focusing on yourself only, your career, and very rare attention towards your wife.
She did not get the chance and hoped that the same subject never came up again. Also, she was a really good wife to you, a really good mother to the child.
Suppose it to be a one-time mistake. What then?
