The Love Hypothesis began as a 2018 Star Wars fan fiction called Head Over Feet. Ali Hazelwood wrote the story around the Reylo pairing of Rey and Kylo Ren before revising and expanding it into the original academic romance about Olive Smith and Adam Carlsen.
That history explains the visual echo readers often notice, but the published novel is not a Star Wars story with different labels. Its setting, professions and central conflict were rebuilt around graduate science, university power and a fake-dating bargain that works for viewers arriving at the story without prior knowledge.

Reylo supplied the original romantic contrast
Reylo is the fan-created name for the relationship between Rey and Kylo Ren in the Star Wars sequel trilogy. The pairing centers on two people positioned as opposites who nevertheless recognize something in each other. Hazelwood’s early story used that tension as romantic material outside the films.

Readers carried an immediate mental image into Head Over Feet: a capable heroine opposite a tall, intimidating man whose severity hides emotional vulnerability. That basic contrast remains visible in Olive and Adam, even after the mythology, conflict and identities around it changed.
Olive and Adam became academic characters
Olive is a Stanford PhD candidate pursuing pancreatic-cancer research. Adam is a professor feared for his blunt criticism and demanding standards. Their shared world is built from grant funding, lab politics and career pressure rather than the Force or a galactic war.
The fake relationship also gives them a new engine. Olive wants her friend Anh to believe she is over Jeremy, while Adam wants Stanford to see him as settled enough to release research money. Their bargain creates regular contact until performance turns into attachment.
The adaptation adds another unexpected connection
Prime Video cast Tom Bateman as Adam. Bateman is married to Daisy Ridley, who plays Rey in the Star Wars films, an off-screen coincidence that gives the adaptation another link to its source inspiration. The movie itself does not turn Olive and Adam back into Rey and Kylo Ren.
Publication also changed the audience’s point of entry. A fan-fiction reader already understood the emotional shorthand behind the original pairing. The novel has to establish Olive’s loss, Adam’s reputation and the pressures of academic life so their attraction works without any Star Wars knowledge.
The path from fan fiction to novel to film shows how a recognizable relationship pattern can become a separate story when its characters acquire new goals, work and consequences. Does knowing the Reylo origin change how you see Olive and Adam? Share your view in the comments.
