The Love Hypothesis is Ali Hazelwood's 2021 debut — the academic fake-dating romance that made STEM rom-com its own subgenre. Olive Smith fake-dates brooding professor Adam Carlsen to convince her best friend her love life is fine. The problem: Adam agrees. Hazelwood's voice — Olive's anxious, self-deprecating internal monologue — launched a thousand imitators and a reader community that pre-orders everything she writes.

Fake dating your tall, infuriating coworker to a wedding in Spain. Same slow-burn structure, same lead voice, same payoff. The most-recommended Love Hypothesis readalike on r/RomanceBooks.
by Emily Henry

by Hannah Grace
Sports romance with the same forced-proximity slow burn and grumpy love interest who melts for exactly one person. Less academia, same emotional payoff.
by Emily Henry
A couple who secretly broke up months ago goes on their annual friend-group trip and has to pretend everything is fine. Same fake-relationship anxiety, deeper emotional stakes.
by Ali Hazelwood
Hazelwood's follow-up — a chess prodigy pulled back into competition by a world champion. Same voice, same female-lead self-doubt, same grumpy love interest formula. The obvious next read.
by Emily Henry
Two writers bet they can write each other's genres in a summer. Henry's best slow burn and the obvious Henry starting point for Love Hypothesis readers making the crossover.
It originated as a Reylo (Star Wars) fan fiction titled Bittersweet. Hazelwood rewrote it as original fiction. Knowing the origin doesn't change the reading experience — it's a complete standalone novel.
One explicit scene — readers who want the spice describe it as "fade to black plus one." Spice level 2 out of 5. The appeal is mostly the slow burn and banter rather than explicit content. Significantly less spicy than Icebreaker or Twisted Love.
Love on the Brain (neuroscientist, enemies-to-lovers, NASA setting) is the consensus answer on Reddit. Under One Roof and Check & Mate are her other well-reviewed follow-ups. All feature STEM protagonists and the same voice.
