To do this, she impulsively kisses the widely-disliked Professor Adam Carlsen, and the two agree to enter into a fake relationship.

Themes In The Love Hypothesis

The Love Hypothesis

(Fake) Romance

At its core, The Love Hypothesis is a romance novel, but it specifically makes use of the fake romance trope.

The fake romance trope is exactly what it sounds like: when two characters put on a show of being in a relationship when they are not really romantically involved.

This is a really interesting way to start a romance novel because both characters are adamant that they are not interested in one another while simultaneously putting themselves into situations and dynamics that can easily spark romantic feelings.


In The Love Hypothesis, one of the main themes is academia – specifically, in the field of STEM.

Olive, the protagonist, is a third-year Ph.D. candidate researching pancreatic cancer, while her love interest, Adam, is a Biology professor.

While the biology lab may not be everyone’s first thought for a romantic setting, this makes the book more interesting since it’s out of the ordinary and allows for some genuine bonding between the main characters.

The academic setting of the novel also contributes a sense of tension and raises the stakes, since this is an environment in which deviating from the rules is frowned upon. And, of course, there’s the issue of the novel’s next big theme…

Workplace Relationships

Because Olive is a Ph.D. student and Adam is a professor, there is inherently a power dynamic in this pairing. This complicates the plot and the relationship between the main characters, as does any workplace relationship.

Workplace relationships are a common theme in romance novels because it’s a great way to have two characters thrown together, even if they don’t like each other at first.

You’ll see coworker and business relationships pop up repeatedly throughout our recommendations, both in scientific fields and in other career paths.

Books Like The Love Hypothesis

The Spanish Love Deception By Elena Armas

The Spanish Love Deception: A Novel

The Spanish Love Deception is a romantic comedy novel that uses the fake dating trope just as expertly as The Love Hypothesis.

However, instead of the romance unfolding in an academic setting, the premise is that the protagonist, Catalina, is looking for a date to attend her sister’s wedding.

It does still have a workplace element, though, so if that’s what you loved about The Love Hypothesis, you’ll enjoy this novel, too.

Catalina has been lying to her family about her relationship status, and now that her sister’s wedding is approaching, the cat is about to get out of the bag.

Unless, that is, she takes up her colleague, Aaron Blackford, on his offer to be her fake date. Despite disliking Aaron, Catalina agrees to bring him to Spain.

As drama and awkwardness unfold, however, her feelings begin to change.


  • Consistent tension and drama keep readers interested
  • Subtle and believable romance
  • Deals with relatable real-life issues


  • Slightly longer than it needed to be

Themes: Fake dating, workplace romance, family dynamics, enemies to lovers, appearances, trust

The Kiss Quotient By Helen Hoang

The Kiss Quotient

If you’re part of the BookTok community, you may already have heard of The Kiss Quotient.

In this novel, the protagonist, Stella, believes that everything in the universe comes down to a mathematical calculation.

Determined to expand on her limited dating experience, Stella hires Michael (an escort) for practice purposes, but she soon begins to realize that no algorithm could have predicted her feelings as her relationship with Michael develops.

As in The Love Hypothesis, there is a central theme of math and scientific theory running through this novel, which only serves to heighten the romantic elements of the plot by contrast.

The Love Hypothesis fans will enjoy watching the once purely transactional dynamic between the two protagonists unfold into something more.


  • Easy to read
  • Well-paced slow burn
  • Explores neurodivergence sensitively


  • Subplots are much less interesting than the main plot

Themes: Romance, math, science, neurodivergence

Beginner’s Guide: Love And Other Chemical Reactions By Six de los Reyes

Beginner's Guide: Love and Other Chemical Reactions (Talking Nerdy Book 1)

Beginner’s Guide: Love and Other Chemical Reactions is the first of two books in the Talking Nerdy series.

The protagonist is Kaya Rubio, who is a twenty-five-year-old research assistant in the field of Molecular Genetics.

Kaya has never been in a relationship and has never particularly wanted one, but her family’s constant pressure leads her to design a scientific method for finding a boyfriend.

When Kaya meets Nero Sison, the complete opposite of everything she thinks she wants in a partner, she sees him as the perfect negative control, but her feelings toward Nero take her by surprise.

Beginner’s Guide presents a different take on the fake dating trope seen in The Love Hypothesis, with one partner rather than both entering into the relationship under false pretenses rather than both parties coming to an agreement ahead of time.


  • Easy and quick to get through
  • Funny and light-hearted
  • A great read for science-lovers


  • The chemistry between the main characters is lacking in places

Themes: Fake dating, science, family dynamics, romance, experiments

Lovelight Farms By B.K. Borison

Lovelight Farms (The Lovelight Series)

Lovelight Farms is different from the other books we’ve recommended for fans of The Love Hypothesis so far, mainly because it doesn’t feature scientific or mathematical themes (apart from the data analyst love interest), or a coworker romance.

However, if you love the fake dating trope and want to see it in other settings, you’ll adore this heartwarming, Christmas-themed romantic comedy.

Stella’s Christmas tree farm is in danger of being closed down, and when she hears of an Instagram competition with a huge cash prize, she jumps at the chance to enter.

However, to win, she needs to make the farm appear to be a romantic destination.

To do this, she convinces her best friend Luka to pretend to be her boyfriend, but it turns out that both Luka and Stella have deeper feelings than friendship for one another.


  • Cute and heartwarming premise
  • Light-hearted, fun mystery subplot
  • Perfect for the holiday season


  • Fairly slow-paced at the beginning

Themes: Holidays, fake dating, friends to lovers, romance

Some Kind Of Magic By Mary Ann Marlowe

Some Kind of Magic (Flirting with Fame Book 1)

Some Kind of Magic is Mary Ann Marlow’s debut novel. The story follows Eden Sinclair, a biochemist, who accidentally enhances her pheromones in the lab one day and attracts the attention of rock star Adam Copeland.

By the time Eden figures out the cause of Adam’s intense interest, the two are already dating.

At this point, Eden is caught in a dilemma: stop using the perfume and risk losing an incredible relationship, or live with the guilt of her secret.

As Eden’s relationship with Adam develops further, the stakes get even higher, and the decision gets all the more difficult to make.

Like The Love Hypothesis, this novel has scientific undercurrents to the romance plot, so if you’re interested in literal chemistry as well as the dating kind, this is the book for you.


  • The interesting and fun main character
  • Witty and amusing throughout
  • The fresh and suspenseful plot


  • Quite slow-paced for the most part

Themes: Chemistry, romance, deception, honesty, moral dilemma

Dating Dr. Dil By Nisha Sharma

Dating Dr. Dil: A Novel (If Shakespeare Were an Auntie, 1)

In Dating Dr. Dil, the reader is introduced to Kareena Mann, who has always dreamed of finding a love like her parents’.

After making a deal with her father to find her soulmate in exchange for the gift of her parents’ house, Kareena meets a cardiologist and host of the Dr. Dil Show, Prem.

When Prem’s reputation is damaged by the public response to his interview with Kareena, the two begin dating in an attempt to salvage his image, but the real feelings that develop are beyond what either of them could have expected.

Another novel that explores the intersection between science and love, Dating Dr. Dil is a great example of both the fake dating and enemies-to-lovers tropes.


  • Strong female protagonist
  • An easy, fast-paced read
  • Some very funny moments


  • Feels repetitive in places

Themes: Science, medicine, love, enemies to lovers, fake dating

Act Like You Mean It By Shae Sanders

Act Like You Mean It

Act Like You Mean It is a fascinating romance novel that plays with the concept of actors pretending to be romantically involved, and takes it offscreen.

In this novel, Hollywood leading man August Chambers is looking for a (fake) girlfriend that his fanbase will approve of to boost his image.

When socialite Xandra Nicole agrees to play the public role of his partner, both parties realize that they are experiencing real feelings for one another… The only problem is, how do you know what’s real or not in Hollywood?

Admittedly, this book might seem quite different from The Love Hypothesis at first, mostly because there’s no scientific theme here.

However, it still has two main characters in roughly the same industry engaging in the fake dating trope.


  • Intriguing premise
  • Romance feels realistic and raw
  • Good character development in a short space of time


  • Fairly slow-paced

Themes: Fake dating, fame, appearances, media, romance

Book Lovers By Emily Henry

Book Lovers

Emily Henry is a very successful romance author, and Book Lovers is one of her most beloved works.

Luckily for fans of The Love Hypothesis, it also features two protagonists in roughly the same line of work: literary agent Nora, and editor Charlie.

When Nora takes a trip to North Carolina, she finds herself running into Charlie repeatedly – something that doesn’t delight either of them.

However, fate seems to want these two book lovers to come together, and that’s exactly what happens, in the most unexpected ways.

Although there’s no fake romance plot line in Book Lovers, the enemies-to-lovers trope is expertly handled, and the shared interest both protagonists share in literature helps to bring them together, similar to Olive and Adam in The Love Hypothesis.


  • Emotional and touching
  • Characters have unique quirks
  • Ideal plot for writers and bookworms


  • Heavy themes sometimes overshadow the romance

Themes: Literature, vacation romance, fate, enemies to lovers

The Hating Game By Sally Thorne

The Hating Game: A Novel

The Hating Game has been adapted for the big screen and is one of bestselling author Sally Thorne’s most well-received works.

It tells a classic enemies-to-lovers story in which colleagues Lucy and Joshua compete for the same promotion, with unexpected consequences.

Joshua and Lucy are complete opposites, despite both working as executive assistants in the same publishing company.

They actively despise each other, but when the tension mounts between them in the run-up to a big promotion, they find that their contempt for one another may mask some more tender feelings.

This workplace romance is the perfect follow-up read for bookworms who loved the colleagues-to-lovers relationship in The Love Hypothesis.


  • Believable use of enemies-to-lovers
  • Fun and easy to read
  • Well-written and developed characters


  • Quite cheesy in places

Themes: Workplace romance, enemies to lovers, opposites attract competition, career, ambition

Battle Royal By Lucy Parker

Battle Royal: A Novel

Anyone who loves the enemies-to-lovers trope and romance between people in the same line of work as in The Love Hypothesis, you’ll really enjoy Battle Royal, particularly if you love baking.

In this novel, Sylvie is a famous baker following her appearance on a popular baking show.

Dominic is famed for being a favorite baker of the King himself and was the one to vote Sylvie off the show years ago. Not only that, but their personalities are total opposites.

Dominic and Sylvie must now compete for the opportunity to bake Princess Rose’s wedding cake, bringing tensions between them to an all-time high in this romantic comedy.


  • Heart-warming concept and story
  • Some funny moments throughout
  • Perfect for baking enthusiasts


  • Lots of minor plots can get confusing

Themes: Baking, competition, enemies to lovers, and opposites attract

The Unhoneymooners By Christina Lauren

The Unhoneymooners

We recommend The Unhoneymooners to readers who enjoyed The Love Hypothesis as well as other similar novels, like The Spanish Love Deception (see above).

This is another book that uses the enemies-to-lovers trope in the context of a destination wedding. It also has a fake romance plot, like the one we see in The Love Hypothesis.

Olive is dreading attending her twin sister’s wedding, and she dreads having to spend time with the groom’s best man, Ethan, even more.

That is until the whole wedding party except Olive and Ethan come down with food poisoning and the two get the opportunity to go on a honeymoon to Maui together.

As they pretend to be a couple, the tension between these sworn enemies begins to soften.


  • Classic enemies-to-lovers story
  • Humorous and light-hearted
  • Good escapism


  • Two authors’ writing styles are identifiable

Themes: Vacation, enemies to lovers, fake dating, family drama

I’m So (Not) Over You By Kosoko Jackson

I'm So (Not) Over You

I’m So (Not) Over You is one of the most interesting takes on the fake dating trope we’ve seen, so it’s the perfect follow-up read for fans of The Love Hypothesis.

In this romantic comedy, Kian Andrews gets a text from his ex, Hudson. As it turns out, Hudson wants Kian to stand in as his fake boyfriend to maintain the image of a relationship while his family are visiting.

Then, in an unexpected turn, Kian is invited to be Hudson’s plus one at a wedding.

Pretending to be romantically involved again has both Kian and Hudson questioning whether their feelings for one another are really in the past after all.

Beach Read By Emily Henry

Beach Read

Beach Read by Emily Henry has been one of the most talked-about romance novels in recent years. If you enjoyed The Love Hypothesis, especially if you’ve also read Book Lovers, this is the romantic comedy for you.

Augustus and January are total opposites of one another. They’re both authors, but while Augusts writes prestigious literary fiction, January is a romance author.

These writers find themselves in beach houses next to each other for three months over the summer, both trying to get over their writer’s block.

Neither one of them would have thought the other could help them out of their predicament until they agree to try swapping genres.

Another novel about two people in the same field of work, this one skips the fake romance and enemies-to-lovers tropes and delivers on feel-good, opposites attract romance.

It’s a great read if you don’t want to deal with a lot of tension and just want a classic romantic comedy to escape into.


  • Funny and feel-good
  • Tackles difficult themes such as depression well
  • An interesting read for literary professionals

The Soulmate Equation By Christina Lauren

However, when she hears about a matchmaking company that pairs people based on their DNA, Jess knows she has to give it a try.

After matching with scientist Dr. River Pena, whom she already knows and has never liked, Jess is confused but agrees to get to know him in order to claim a monetary reward from the company.
