In a world of scripted romances that often fizzle under scrutiny, the chemistry between Nick and Noah in Mercedes Ron’s Culpables trilogy stands out as palpably real, igniting a global obsession that’s only intensified with the October 16, 2025, Prime Video release of the finale, Culpa Nuestra (Our Fault). Portrayed by Gabriel Guevara and Nicole Wallace, the step-siblings-turned-lovers have captivated audiences since the 2023 debut Culpa Mía (My Fault), evolving from a steamy teen drama into a cultural phenomenon. Fans rave that “you can’t fake that kind of chemistry,” a sentiment echoed across social media as the series wraps its arc of passion, betrayal, and redemption. With the third installment streaming now, the question lingers: Has the saga earned its happy ending, or does it crumble under its own dramatic weight?

The Culpables trilogy, adapted from Ron’s bestselling YA novels, follows Noah Morgan (Wallace), a rebellious teen uprooted from her life in the U.S. to Spain after her mother’s whirlwind marriage to a wealthy widower. There, she clashes—and inevitably falls—for Nick Leister (Guevara), her brooding new stepbrother and heir to a luxury car empire. What begins as a hate-to-love trope laced with forbidden tension explodes into a whirlwind of jealousy, secrets, and high-stakes drama. The first film, My Fault, dropped on Prime Video in June 2023, amassing over 60 million views in its first month, thanks in large part to the leads’ electric on-screen dynamic. Scenes like their rain-soaked first kiss—charged with defiance and desire—became instant GIF fodder, with fans on X (formerly Twitter) declaring it “the hottest makeout in movie history.”

Guevara, 23, and Wallace, 22, both alumni of the Spanish YA series Skam España, bring an authenticity that’s hard to replicate. Their real-life friendship, forged on that set, translates into a gaze that lingers just a beat too long, touches that feel improvised, and arguments that simmer with unresolved heat. “No one could’ve brought Nick and Noah to life the way Gabriel and Nicole did,” tweeted fan @xhesbizzle on October 16, a post racking up 845 likes and echoing a chorus of sentiments. Off-screen, the duo’s playful banter during press junkets—Guevara teasing Wallace about her “feisty” improv—only fueled shipping rumors, though they’ve insisted it’s all professional magic. In a 2023 interview with Elle España, Wallace credited their bond: “We trusted each other completely. That vulnerability? It’s what makes the chemistry pop.”

The sequel, Culpa Tuya (Your Fault), released in December 2023, cranked up the stakes. After a devastating betrayal—Noah’s fling with Nick’s rival, Mario— the couple splits, sending Nick to London for a fresh start. The film, which introduced a remix vibe with English dubbing options, drew mixed reviews for toning down the toxicity but amplifying the longing. Fans on Reddit’s r/romancemovies subreddit debated endlessly: One user praised the “insane chemistry” in a rain-drenched reunion scene, while another lamented the loss of Noah’s “feisty vulnerability” from the original. Still, it held strong, with 40 million streams and viral clips of Nick’s jealous glares dominating TikTok edits set to The Weeknd’s “Heartless.”

Enter Our Fault, the trilogy’s emotional payoff, directed by Domingo González. Picking up a year post-breakup, Noah has rebuilt in Barcelona, studying law and dodging her past, while Nick returns from London a changed man—tattooed, world-weary, and still hopelessly in love. Their reunion at a wedding spirals into a one-night stand laced with unresolved fury, forcing both to confront if forgiveness can trump their scars. Spoiler alert (for the brave): Without diving too deep, the film delivers the “happy ending” fans craved—a surprise pregnancy, a heartfelt proposal, and a family forged from chaos—but not without gut-wrenching detours, including a kidnapping scare and family meddling that tests their limits. As one X user posted, “Nick and Noah’s passionate romance… I’m crying. This is the end and we won’t see them again.”

Critics have been kinder to the finale than the franchise’s pulpy roots might suggest. Variety called it “a satisfying capstone, buoyed by Guevara and Wallace’s lived-in rapport,” awarding it a 7/10 for balancing spice with substance. The chemistry peaks in quieter moments: Nick tracing Noah’s tattoo in a candlelit scene, or her whispering apologies during a midnight drive. But detractors, like those on IMDb forums, slam the plot as “cliché-ridden,” pointing to over-the-top twists—like a vengeful ex’s sabotage—that strain credulity. “The leads sizzle, but the script fizzles,” one reviewer quipped. Box office-wise, while theatrical runs were limited in Spain, Prime Video reports it’s the platform’s top non-English film of the week, surpassing even The Idea of You in global hours watched.

Fan fervor has turned the trilogy into a social media juggernaut. On X, #CulpaNuestra trended worldwide post-release, with 2.5 million mentions in 48 hours. Posts gush over the leads’ “beyond fiction” spark—@Samah5kais shared a clip of their first kiss, captioning it “passionate, spicy, so real”—while edits mash up scenes with Bad Bunny tracks for that extra Latin heat. Reddit threads dissect Easter eggs, like callbacks to My Fault‘s closet confrontation, and Wattpad alums (the books originated there) celebrate the faithful adaptation. Even skeptics admit the pull: “They have chemistry… but that doesn’t mean they have to be together,” one NetGalley reviewer conceded, highlighting the saga’s toxic undertones.

Off-screen, Guevara and Wallace have navigated their own spotlight. Both faced scrutiny—Guevara for past legal issues in 2023, Wallace for defending him publicly—but their poise mirrors Nick and Noah’s resilience. At a Madrid premiere on October 15, they posed arm-in-arm, Wallace in a crimson gown echoing Noah’s fiery spirit, Guevara in tailored black channeling Nick’s edge. “This trilogy changed us,” Guevara told reporters. “Playing these roles? It’s like living a fever dream.” Wallace added, “The fans see the love because it’s real—for the characters, and for the story we told.”

As Our Fault streams, the debate rages: Is this chemistry the stuff of legends, or just YA escapism? For devotees, it’s both—a reminder that some sparks, like Nick racing through Barcelona rain to claim Noah, burn too bright to extinguish. Ron’s novels have sold 5 million copies worldwide, and whispers of spin-offs (perhaps Mario’s redemption?) swirl. Until then, fans cling to the finale’s closing line: “Our faults made us whole.” In a genre crowded with fakes, Nick and Noah proved one truth—you can’t script what the heart feels.
