Gabrielle Zevin’s third-person narrative, Tomorrow, and Tomorrow, and Tomorrow, follows the friendship of Sadie and Sam over the course of thirty years. At the outset of the novel, the characters reconnected for the first time since childhood, in a subway station. Before Sadie boarded her train, she gave Sam a disc with a copy of her new game, Solution. When they were young, Sam and Sadie met in the hospital and talked about Nintendo and Oregon Trail. After their first meeting, the nurses asked Sadie to return to help Sam’s recovery, and her mother promised she would receive community service hours. When Sam discovered that Sadie had ulterior motives, he felt betrayed and stopped talking to her. In the narrative present, Sam went to Sadie’s apartment to discuss Solution. She was struggling with depression and explained that she went through a bad breakup. Although she did not tell Sam, Sadie had been dating her professor, Dov, who left her to rekindle his relationship with his wife. Sam continued to visit Sadie and later proposed that they develop a game together.

Sam and Sadie worked on Ichigo in Marx’s apartment the summer before their senior year. When Sam suggested that Sadie ask Dov for the engine Ulysses, Sadie agreed and begins dating the professor again. Ichigo was well received, and the friends sold the game to Opus, who contracted them for a sequel. However, when Ichigo II was met with lackluster reviews, Sadie conceptualized a new game, Both Sides. Unfair Games moved to California during the production of their third game. The move helped Sam to recover from his surgery and gave Sadie and excuse to end her relationship with Dov, who was increasingly abusive. In California, Sam struggled with phantom limb syndrome, loneliness, and excruciating pain. However, Sadie felt rejuvenated and happy for the first time. However, when she discovered that Sam knew about her relationship with Dov, before pushing her to contact him for the engine, she felt betrayed. Sadie blamed Sam for not protecting her, even though she never spoke openly about her relationship with Dov. Their friendship was increasingly strained, and their communication indirect. Later, Sadie began to date their business partner and friends, Marx.

After the successful release of Sadie’s game, Master of Revelers, Sam and Sadie attempted to reconcile their relationship. The friends went on a press tour to promote the game. However, when they are away, Sadie discovered she was pregnant, and Marx was shot by a gunman who entered the office looking for Sam. The shooter was angry that Unfair created same sex marriage in their game Mapleworld and shot Marx and Ant. After her partner’s death, Sadie refuses to talk to Sam or visit the office. Meanwhile, Sam led Unfair Games forward and oversaw the completion of Counterpart High: Senior Year. When the game was finalized, he organized a party for his employees. Despite the revelry, Sam felt alone without either of his partners. As years passed, Sam and Sadie both contemplated contacting each other but were unsure how to reconcile the distance. Dong Hyun encouraged Sam to speak to his oldest friend and later left his Donkey Kong machine to Sadie, in his will. Sam called Sadie shortly after to inform her of the inheritance. Later, the friends travelled to New York to speak with another company about developing Ichigo III. In the airport, Sam suggested that they make another game together and Sadie gave him a disk with her new game, Locus Sextus.
