Chapter 20 Summary

Olive goes to the restaurant where Harvard’s biology department took Adam for dinner. She plans to surreptitiously get Adam’s attention and motion for him to check his phone before leaving, but he sees her immediately and leaves his dinner meeting to talk to her. Tom interrupts them, and Adam orders him to leave, his “voice low and cold” (324). Tom refuses to go, and Olive starts playing the recording of Tom’s insults.


Adam explodes with anger, threatening to kill Tom if he says anything else about “the woman [he] love[s]” and throwing him against the wall (326). Olive begs him to stop. He does and goes to her, comforting her before answering to the confused and angry Harvard professors. Adam says he will take care of everything with Harvard. When he’s done, he’ll find Olive and “take care of [her]” (327).

Chapter 21 Summary

At the San Francisco airport, Olive and Malcolm wait for Adam and Holden’s flight to land. Olive checks her email and finds four messages from researchers who’d love to have Olive in their labs, one of which is local. Shortly after, Adam and Holden arrive, and Holden proposes the four of them have dinner together. Adam doesn’t want to go, but Olive talks him into it. Adam says “we” will go, and his “we” sounds like “he and Olive were a ‘we,’ like it had never been fake after all” (333).


At dinner, Holden calls Adam out on mean things he said about Malcolm’s research in the past. Adam has no recollection of this but apologizes, citing Olive’s observation that he can be moody and unapproachable. She and Adam share a look, and everything about them feels right. Holden and Malcolm argue about a pumpkin spice tea that’s on the menu, Malcolm sounding a lot like Adam when he criticizes Olive’s love for sugary drinks.


The conversation works around to how Adam’s been into Olive for years, as compared to how Holden and Malcolm’s relationship is so new. Olive is confused until Holden explains that Adam had been talking about her since they met in the bathroom before her interview. Olive realizes she was right. The man in the bathroom really was Adam, and he’d remembered her, too.

Chapter 22 Summary

On their way out of the restaurant, Olive grabs fortune cookies for each of them. Holden and Malcolm’s are backward advice while Olive’s says she can tell the truth—something she resolves to do more. Adam refuses to eat his cookie, so Olive does and gives him the fortune, which reads “you can fall in love: someone will catch you” (342).


Adam walks Olive to her apartment, and on the way, they discuss Tom. He will be fired, and other disciplinary actions are still being decided. Olive tells Adam she remembered him from the bathroom, too. She asks why he never said anything, and he tells her it’s because she never let on that she remembered him. They stop outside her apartment, where Olive confesses that she never had feelings for Jeremy and tells Adam she loves him.

Epilogue Summary

Ten months later, it’s one year to the day when Olive kissed Adam in the biology lab to make Anh think she had a boyfriend. Olive recreates the experience, even setting an alarm on her phone to kiss him at the exact same time. When the alarm goes off, she leans into him, stands on her tiptoes, and whispers into his ear, “May I kiss you, Dr. Carlsen?” (352).

Chapter 20-Epilogue Analysis

In the novel’s final section, Hazelwood fulfills the expectations of the romance genre by giving Olive and Adam their happily ever after. Adding to the resolution’s satisfaction, Tom faces the consequences of his abusive behavior, ensuring that he is no longer a threat to either Olive or Adam. The four emails from professors show how Tom’s opinion was false. Olive’s work is good enough to garner attention from several universities. The interest of a local researcher means Olive can stay in California with Adam, who turned down the job offer from Harvard in a testament to his commitment to building a future with the protagonist.


The dinner with Holden and Malcolm represents Olive’s two worlds joining, the one of her friends who are students and her boyfriend who’s a professor. As a student in the biology department and one of Adam’s grads, Malcolm has had a rocky relationship with Adam, which is also resolved. Malcolm’s rant about sugary drinks shows he and Adam have more in common than either thought. This offers an encouraging sign that Malcolm and Adam will have a better relationship moving forward, underscoring the happy merging of the various facets of Olive’s life.


The discussion about the bathroom conversation two years ago brings the novel full circle. Olive realizes she was right that the man was Adam, which makes her relationship with him feel even more secure. The epilogue in a romance novel often shows either the main couple getting married or having children. However, Hazelwood’s STEM romance subverts this by having the main characters recreate their first kiss rather than take on a new form of commitment in the epilogue. The scene also nods to Olive’s scientific nature’ she claims that she wants to repeat the “experiment” of their initial kiss to make sure her relationship results with Adam aren’t a fluke. This playful invocation of the scientific method reflects the novel’s distinct subgenre as a STEM romance.
