The Love Hypothesis
Fake dating a grumpy professor in the lab where feelings are the real experiment
By Ember · Updated July 2, 2026
The Love Hypothesis is STEM-girl wish fulfillment in the best possible way. Olive needs a fake boyfriend to prove she's moved on, and Adam, the intimidating professor everyone fears, agrees to the charade. What follows is a romance that respects both the science and the feelings.
Adam Carlsen is peak grumpy/sunshine done right. He's not an asshole who needs fixing, he's competent, kind beneath the scowl, and supportive in ways that matter to Olive's career. The way he advocates for her, believes in her research, and dismantles her imposter syndrome is as romantic as any grand gesture.
Hazelwood writes academia accurately enough that the setting feels real without bogging down the romance. The lab politics, the funding struggles, the pressure to publish, it all grounds the fake dating hijinks in a world that STEM women recognize.

What you're really after when searching for books like The Love Hypothesis
You want smart women in STEM fields finding romance that doesn't require them to dumb themselves down or abandon their ambitions. Heroines whose careers are as important as their love lives, with heroes who support rather than compete with their success.
You're looking for that specific grumpy/sunshine dynamic where the grump is secretly soft for exactly one person. Fake dating that turns real, the delicious tension of maintaining the lie while feelings develop, the moment when pretending becomes impossible.
What you're craving is romance that feels like representation, where the heroine's neurodivergent traits, her passion for science, her imposter syndrome, and her career ambitions are all part of what makes her lovable, not obstacles to overcome for romance.

Common questions
Is The Love Hypothesis spicy?
Moderately. There's definitely steam, but it's not the primary focus. The tension and romance build slowly, with the physical relationship developing alongside the emotional connection.
Do I need to understand science to enjoy it?
Not at all. The science is present but accessible. You get enough to feel the authenticity of the academic setting without needing a biology degree to follow the plot.
Is this enemies to lovers?
Not quite. Olive thinks Adam hates her, but he doesn't, she's misreading his grumpy exterior. It's more grumpy/sunshine with fake dating than true enemies to lovers.
Are there any trigger warnings?
There's mention of a past kiss that crossed consent boundaries, academic sexism, and family pressure. The book handles these topics with care, but they're present.
