The paradox of long-term male and female relationship
The primary paradox is that Sam and Sadie started their friendship at the age of eleven, it later lasted for over three decades, and they never felt sexually intimate with each other. The only thing that bonded these two opposite-sex friends was their passion and shared interests. Consequently, the love story between Sadie and Sam is based on mutual interest, not romance. While at college, Sadie used to sleep with her professor, and she was open about it.
The conflict between Sadie and Sam
Sam and Sadie could sometimes have fierce arguments regarding their game creations. Sam strongly believed that a game should be simple and entertaining, while Sadie strictly wanted the games to be complex and be based on beauty and complexity. Interestingly, despite having fierce arguments, Sadie and Sam came into an agreement to produce a game that put their names in the international entertainment arena.
The meeting at the Harvard subway
After many days, Sam and Sadie meet at the Harvard car subway. Sam immediately recognizes her among the crowd, and he shouts her name loudly. Sam could not hide his joy after seeing the woman who helped his recovery from trauma while at the hospital when they were young. Ironically, Sadie pretends that she does not hear her name being called and behaves like she doesn't know Sam. However, she later accepts that she is Sadie, and they start their dream of making a difference in the gaming industry.
