There’s a specific kind of unhinged behavior that comes with reading a grumpy x sunshine romance in public. You’re sitting in a coffee shop, minding your business, and then the brooding hero who hasn’t smiled since 2019 does something impossibly tender for the sunshine FMC — and suddenly you’re making noises. Weird noises. The barista is concerned.
I get it. I am you.
The grumpy x sunshine trope is basically crack for romance readers, and BookTok knows it. One character is a walking thundercloud. The other is aggressively cheerful. They shouldn’t work together. They absolutely work together. The tension between a grump slowly thawing and a sunshine character refusing to be dimmed? Chef’s kiss. Every time.
But here’s the thing — not every grumpy x sunshine book actually delivers. Some of them give you “mildly inconvenienced” instead of genuinely grumpy, or “pleasant” instead of true sunshine energy. So I went through and picked the ones that actually nail the dynamic. The ones where you can feel the grump softening and it makes your chest do weird things.
Here are 10 books that do grumpy x sunshine so well you’ll want to throw your Kindle across the room (affectionately).
1. The Love Hypothesis by Ali Hazelwood
Okay yes, everyone and their mother has read this one. But it’s the grumpy x sunshine GOAT and I’m not going to pretend otherwise. Adam Carlsen is the grumpiest man in all of academia — intimidating, blunt, allegedly terrifying to grad students. Olive Smith is a PhD candidate who fake-kisses him in a moment of panic and somehow ends up in a fake relationship with a man who looks like he’d rather be literally anywhere else.
Except he wouldn’t. Because Adam is soft for Olive in ways that will make you feral. The scene with the tomatoes? Unrecoverable. If you haven’t read it, I’m genuinely jealous that you get to experience it for the first time.
2. The Hating Game by Sally Thorne
This book walked so every office romance could run. Lucy and Joshua share a desk (facing each other — actual nightmare) and have been locked in a rivalry for years. She’s bubbly, optimistic, wears color. He’s tall, cold, wears only black and grey. They play mind games. They have a scoring system. It’s completely unhinged.
And then you find out why Joshua is the way he is, and suddenly you’re the one being emotionally destroyed. Sally Thorne wrote the tension so thick in this book you could cut it with a letter opener. The elevator scene lives rent-free in my brain.
3. Beach Read by Emily Henry
January is a romance writer going through it — dead dad, cheating scandal, creative block. Augustus is her next-door neighbor for the summer and a literary fiction author who probably thinks happiness is a bourgeois construct. They challenge each other to swap genres for the summer, and somewhere between the research trips and the late-night arguments about storytelling, they fall for each other.
What makes this one special is that both characters are dealing with real, heavy stuff. The sunshine isn’t performative — January is actively fighting to stay hopeful. And Gus’s grumpiness isn’t just a personality trait; it’s armor. When it cracks? Devastating. In the best way.
4. Things We Never Got Over by Lucy Score
Naomi shows up in a small town in Virginia after her twin sister steals her car and abandons a kid. Knox is the local grump who wants nothing to do with her drama. He’s also the hottest guy in town and everyone’s a little scared of him. Naturally, Naomi ends up needing his help.
This is a long book — like 550+ pages — and honestly? Every page earns its spot. Knox is grumpy in the “I will actively pretend I don’t care about you while rearranging my entire life around you” way, and Naomi is sunshine in the “I will bulldoze your walls with kindness” way. The chemistry is absurd. Lucy Score really said “what if I made the slow burn 500 pages” and you know what? It works.
5. People We Meet on Vacation by Emily Henry
Yes, Emily Henry is on this list twice. She’s earned it. Alex and Poppy are best friends who take a vacation together every summer — she’s chaotic and extroverted, he’s quiet and a creature of routine. Two years ago, something happened on their trip to Croatia that ruined everything. Now Poppy is trying to fix it with one last vacation.
Alex is the most lovable grump because he’s not mean, he’s just… Alex. He folds his clothes into his suitcase like an accountant. He brings a book everywhere. He probably has opinions about thread count. And he has been in love with Poppy for approximately forever. The dual timeline thing — alternating between past trips and the present — is so well done it should be studied.
6. The Spanish Love Deception by Elena Armas
Catalina needs a date to her sister’s wedding in Spain. Aaron Blackford — her insufferable, arrogant coworker — volunteers. She’d rather eat glass. But beggars can’t be choosers, and she is, in fact, begging.
What follows is a fake-dating setup where you watch Aaron go from “emotionally constipated colleague” to “man who would rearrange the stars for this woman” in real time. He’s grumpy in a quiet, measured way — the kind of guy who shows he cares through actions while his face remains completely neutral. Catalina’s warmth basically short-circuits him and it’s beautiful to watch. Also it’s set in Spain. So the food descriptions alone are worth the read.
7. Icebreaker by Hannah Grace
Anastasia is a figure skater — graceful, positive, works hard, plays harder. Nate is the hockey team captain who is essentially allergic to fun. When a rink-sharing situation forces them into each other’s orbit, the ice melts. Literally and figuratively. (Sorry. Had to.)
This one is spicier than most on the list, so heads up. But beyond the steam, what makes it work is that Nate’s grumpiness comes from genuine pressure and responsibility, and Stassie’s sunshine isn’t naive — she’s just decided life is too short to be miserable. BookTok went absolutely feral for this one, and honestly? Justified.
8. Promise Me Sunshine by Cara Bastone
This one’s newer (2025) and it hit me way harder than I expected. Lenny is grieving her best friend and doing that thing where you’re technically alive but not really living. Miles is grumpy, guarded, and dealing with his own stuff. He offers to help her work through a bucket list her friend left behind.
It sounds like it could be saccharine, but Bastone doesn’t let it be. The grief is real. The healing is messy. And the romance builds so gradually that when it finally lands, it feels earned in a way that most books dream about. If you want grumpy x sunshine with genuine emotional weight, this is the one.
9. The Wall of Winnipeg and Me by Mariana Zapata
Mariana Zapata is the queen of slow burn, and this might be her best work. Vanessa quits her job as the personal assistant to Aiden Graves — a massive, silent, professional football player who barely acknowledges her existence. Then he shows up at her door asking her to come back. And also marry him. For a green card.
Aiden is grumpy in the way that mountains are grumpy. He’s just there. Immovable. Expressionless. Using as few words as possible. And Vanessa is all fire and personality and “I will not be ignored.” The slow burn in this book is genuinely torturous — in the best way. You’ll be screaming at your book for these two to just COMMUNICATE. But when they finally do? Worth every agonizing page.
10. You Deserve Each Other by Sarah Hogle
Here’s a weird one — the grumpy x sunshine dynamic, but make it a couple that already hates each other. Naomi and Nicholas are engaged and both want the other person to call off the wedding (because whoever cancels has to face the social fallout). So they start trying to annoy each other into breaking up.
It’s petty. It’s hilarious. And somewhere in the middle of their war, you realize they used to be grumpy x sunshine — he was the grump, she was the sunshine — and life just ground them both down. Watching them find their way back to each other instead of falling in love from scratch? Unexpectedly emotional. Sarah Hogle is so funny it should be illegal, and this book proves that grumpy x sunshine can work even after the honeymoon phase is long dead.

Look, I could keep going. This trope has infinite replay value because the core dynamic — someone who is dark and closed-off being slowly undone by someone bright and persistent — never gets old. It’s comfort reading with teeth.

Now if you’ll excuse me, I need to go reread The Love Hypothesis for the fourth time and pretend Adam Carlsen is a real person. Don’t judge me. You’re here too.
