If you loved 'The Temporary Roomie' for its blend of romantic tension and forced proximity, you're in for a treat with these picks. First, 'The Unhoneymooners' by Christina Lauren is a hilarious enemies-to-lovers story where two rivals end up sharing a honeymoon suite—fake relationship included.

If you enjoyed the twisted romance and psychological intensity of 'The Perfect Girlfriend', you might dive into 'Gone Girl' by Gillian Flynn. The unreliable narrators and mind games in both books create this addictive, unsettling vibe that keeps you questioning every character's motive. Another dark gem is 'The Girl on the Train' by Paula Hawkins—less about obsession and more about fractured perception, but it nails that 'what’s real?' tension. For something with a more calculated, icy protagonist, 'The Kind Worth Killing' by Peter Swanson has a similar cat-and-mouse allure, though it leans harder into thriller territory. What fascinates me about these books is how they blur love and danger, making you root for people you absolutely shouldn’t.

Kasie West’s 'The Fill-In Boyfriend' is one of those books that sneaks up on you with its charm. At first glance, it seems like a straightforward YA romance—girl hires a stranger to pretend to be her boyfriend at prom to save face after a breakup. But what unfolds is this delightful exploration of identity, expectations, and the messy, often hilarious ways we try to control how others see us. Gia, the protagonist, starts off as this perfection-obsessed girl, but her dynamic with the fill-in boyfriend, Hayden, forces her to confront how much of her life is performative. Their chemistry is electric, and West nails the slow burn of two people peeling back each other’s layers. The supporting cast adds so much depth, too—Gia’s friendships and family relationships aren’t just background noise. They shape her choices in ways that feel real, especially the tension with her sister. The book’s strength lies in how it balances light, swoony moments with genuine emotional weight. If you’re into stories where the romance feels earned and the characters grow beyond their tropes, this is absolutely worth your time. Plus, the dialogue is sharp enough to make you laugh out loud in places.

The main character in 'The Fill-In Boyfriend' is Gia Montgomery, a high school senior who's used to being in control of her social image. When her boyfriend dumps her right before prom, she panics and convinces a stranger named Hayden to pretend to be him for the night. What starts as a desperate lie turns into a messy, heartfelt journey as Gia navigates the consequences of her deception. I love how Kasie West writes Gia—she's not just your typical popular girl. Underneath that polished exterior, she's dealing with family pressure, insecurities, and the realization that her 'perfect' life might not be what she truly wants. The way her relationship with Hayden develops feels organic, especially as he calls her out on her flaws. It's one of those books where the fake dating trope actually serves a deeper purpose, pushing Gia to grow beyond her shallow concerns.

If you loved the quirky, heartwarming vibes of 'Buy a Boyfriend', you might enjoy 'The Love Hypothesis' by Ali Hazelwood. It’s got that same fake relationship trope but with a hilarious academic twist—imagine pretending to date your lab partner to convince your friends you’re over your ex. The banter is top-tier, and the emotional payoff feels just as satisfying. Another gem is 'Beach Read' by Emily Henry, where two rival authors swap genres and accidentally fall for each other. It’s got that blend of humor and deep emotional moments that made 'Buy a Boyfriend' so addictive. For something with a bit more fantasy flair, 'The Kiss Quotient' by Helen Hoang is a must. It follows a woman with autism who hires an escort to teach her about relationships, and the dynamic is both sweet and steamy. If you’re into manga, 'Wotakoi: Love Is Hard for Otaku' is a hilarious take on awkward adult relationships, especially if you enjoy nerdy protagonists stumbling through love. The pacing and humor remind me of 'Buy a Boyfriend', but with a gamer twist. Honestly, any of these will scratch that itch for a rom-com with depth and charm.

I picked up 'The Boyfriend Goal' because I love a messy, warm sports romance that doesn’t take itself too seriously, and wow — it delivers on swoon and awkward-lovable moments. The book follows a librarian heroine who gets tangled up with a hockey player, and that setup (one-night chemistry turning into more complicated feelings, plus a brother/teammate dynamic) gives the story a cozy-still-spicy energy that hooks you fast. The tone is playful, the banter lands, and if you like your romance with both heat and heart, this one hits those beats nicely. Reading it felt like hanging out with a friend who’s equal parts sincere and mischievous: there are laugh-out-loud scenes, true emotional growth for both leads, and some locker-room sport worldbuilding that actually mattered to the characters instead of just being a backdrop. Reviewers and fellow readers have called it a fun, flavorful sports romance with tropes people adore — roommate/teammate complications and that irresistible “forbidden-but-right” pull. If you’re picky about character development, you’ll find moments that dig deeper than pure surface fluff. If you want similar vibes, try 'The Deal' by Elle Kennedy for a college hockey romance with sharp banter and big emotional payoff, and 'Pucked' by Helena Hunting if you prefer a raunchier, laugh-loud rom-com in the hockey world. Both lean into the sports-chemistry axis in different ways, so they’re perfect follow-ups depending on whether you want more feels or more nonsense-with-heart. I came away from 'The Boyfriend Goal' smiling and already imagining which brother/teammate character I’d root for next.

Ever since I stumbled upon 'Fake Boyfriend but His Kiss', I've been craving more stories with that perfect blend of fake relationships turning real and electric chemistry. If you loved the tension and slow burn, you might adore 'The Love Hypothesis'. It nails the academic rivals-to-lovers trope with a fake dating twist, and the banter is just chef's kiss. Another gem is 'Red, White & Royal Blue', where the fake friendship between a prince and the First Son spirals into something way more intense. The political backdrop adds depth, but it's their stolen moments that'll make you swoon. For something lighter, 'To All the Boys I’ve Loved Before' has that sweet, awkward charm—fake dating a family friend? Messy but adorable.
