Nicole Wallace and Gabriel Guevara have become synonymous with the passionate, forbidden romance of the Culpa trilogy, captivating audiences as step-siblings Noah and Nick in Prime Video’s adaptations of Mercedes Ron’s bestselling novels. Their electric chemistry in Culpa Mia (2023) and Culpa Tuya (2024) not only propelled the films to global streaming records but also ignited endless fan theories about a real-life connection. From playful interviews to red carpet camaraderie, the pair’s rapport suggested a bond that transcended scripts. Yet, as Culpa Nuestra (2025) wraps the saga, recent events have shifted the narrative toward distance and maturity, reminding viewers that Hollywood’s closest co-stars often keep their personal lives just out of reach.

The duo’s journey began with Culpa Mia, where Wallace, then 21, and Guevara, 22, brought Ron’s Wattpad sensation to life. Noah, a resilient teen navigating family upheaval, and Nick, a brooding racing heir, share intense, push-pull dynamics that mirror the actors’ own youthful energy. Behind the camera, their friendship blossomed quickly. Wallace, known for her role in El secreto de Puente Viejo, and Guevara, fresh off Skam España, bonded over long filming days in Madrid. In a 2023 Variety interview, Wallace described their prep: “We spent hours discussing our characters’ backstories—it felt like therapy.” Guevara echoed this, telling El País, “Nicole brings out the best in scenes; her laugh lightens everything.” Fans latched onto these glimpses, flooding social media with edits of their laughs and shared glances, dubbing them “the real deal.”

This synergy translated seamlessly to screen. Culpa Mia debuted as Prime Video’s most-watched non-English film, amassing over 100 million views in weeks. Critics praised their natural interplay—Wallace’s fiery vulnerability complementing Guevara’s quiet intensity—earning a 6.2 IMDb rating despite mixed reviews on plot predictability. Off-screen, they amplified the hype: Joint Instagram Lives drew millions, with Guevara teaching Wallace racing tips and her sharing makeup hacks. At the 2023 premiere, they arrived hand-in-hand (as friends, per their teams), posing for photos that screamed insider comfort. “We’ve known each other since our teens through mutual projects,” Wallace clarified in a Hola! feature, emphasizing a “great working relationship.”

Rumors of romance peaked during Culpa Tuya‘s promo tour. Fans dissected every interaction: A November 2023 clip of them reading fan mail, giggling over “ship names,” went viral with 5 million TikTok views. Guevara’s protective arm around Wallace at events fueled speculation, especially after his on-off relationship with model Agostina Kolodziej ended around filming. “Their vibe is too real,” one Reddit thread in r/romancemovies opined, with users sharing timelines of “flirty” interviews. Wallace addressed the buzz lightly on Instagram: “Love you all, but we’re just besties making magic.” Guevara, in a GQ España profile, joked, “If we dated, the tabloids would explode—but nah, it’s all Noah and Nick.”

The turning point came post-Culpa Tuya filming in late 2023. On November 1, Wallace unfollowed Guevara on Instagram, sparking a frenzy. Sources close to production told The Direct of a “public disagreement” on set, though details remained vague—possibly creative differences or personal boundaries. Social media amplified the drama: Guevara liked posts praising Wallace’s work but faced backlash for allegedly engaging with critical comments, later deleted. By early 2024, Guevara confirmed dating actress María de Nati, sharing cozy photos that quashed crossover theories. “We’re friends and colleagues—nothing more,” he stated at a Culpa Tuya event, while Wallace reiterated their “professional respect.”

Tensions simmered publicly during the December 2024 Culpa Tuya premiere in Madrid. Photos showed them posing separately with author Ron and director Eduard Cortés, and a TikTok clip captured Wallace stepping away from a joint photo op. Fans mourned the shift: “#NicoleAndGabriel” trended with 200,000 posts, blending heartbreak over lost “endgame” vibes and support for their space. Speculation swirled—some blamed De Nati’s discomfort with fan shipping, others cited filming fatigue for Culpa Nuestra, shot back-to-back. A viral X thread dissected the unfollow as “mutual growth,” gaining 50,000 likes.

Yet, maturity prevailed. For Culpa Nuestra‘s October 2025 release, directed by Domingo González, they reunited professionally. A promotional video surfaced showing them reading note cards in Spanish, bodies relaxed and smiles genuine—though scripted, it eased concerns. In it, Guevara reflected on their characters’ “toxic elements,” adding, “Real love needs health and destiny.” Wallace, promoting her upcoming Intimidad series, told IndiaTimes, “We’ve always had mutual respect; bumps happen in any close collaboration.” The film itself explores jealousy and reconciliation, mirroring their arc: Nick and Noah face tests but choose forgiveness, much like Wallace and Guevara’s reported behind-the-scenes talks.

Culpa Nuestra debuted to 5.4 IMDb stars, lauded for emotional depth but critiqued for stiff chemistry—some attributed to off-screen distance, others to narrative fatigue. Still, it shattered records as Prime Video’s top non-English title, with 120 million hours viewed globally. Fans on X celebrated: “Their real bond made the trilogy—hoping for a happy off-screen ending too.” Post-premiere, they shared a stage at a Madrid panel, discussing growth: “Filming taught us about boundaries,” Guevara said, with Wallace nodding.

Wallace and Guevara’s story reflects Hollywood’s double-edged sword: On-screen intimacy breeds off-screen curiosity, but privacy protects authenticity. Wallace, now 24, stars in Netflix’s La Mesías, earning acclaim for dramatic range. Guevara, 25, headlines Vacaciones de Verano, balancing rom-coms with depth. Both credit the trilogy for launches—Wallace’s followers surged 300%, Guevara’s by 250%—but emphasize separation: “Noah and Nick are fiction; we’re just us,” Wallace posted in a subtle nod.

In fan spaces like Tumblr and Wattpad, their “feud” inspired fanfic exploring “what ifs,” while positive threads highlight resilience. A FandomWire piece noted, “Their journey shows co-stars can evolve beyond roles.” As the trilogy closes, so does a chapter: From inseparable promo partners to respectful pros, Wallace and Guevara prove chemistry endures—in art, if not always in life.

Their saga leaves a lesson: True connections weather rumors. With new projects ahead, expect more collaborations—or not—but always that undeniable spark. For now, Noah and Nick’s finale offers closure, while Nicole and Gabriel chart their own paths.
