My Fault: London vs Culpa Mía – Which Steamy Step-Sibling Romance Truly Deserves Your Time in 2025?

I’ve been completely obsessed with these two steamy step-sibling romances on Prime Video lately, and I need to talk about them! If you haven’t checked out “Culpa Mía” or its English remake “My Fault: London” yet, you’re seriously missing out. Both films are based on Mercedes Ron’s wildly popular Wattpad novels that later got published as the “Culpables Saga” trilogy.

“Culpa Mía” currently sits at a respectable 6.3/10 on IMDb, while “My Fault: London” is slightly higher at 6.7/10. On Rotten Tomatoes, critics weren’t too kind to either film, but audiences gave “My Fault: London” a solid 75% approval rating compared to “Culpa Mía’s” 70%. But numbers don’t tell the whole story!

You can stream both movies exclusively on Amazon Prime Video right now. The Spanish “Culpa Mía” also has a sequel called “Culpa Tuya” already available, with a third film coming later this year. The English version just dropped in February 2024, so we’re still waiting on news about its potential sequels.

Is My Fault: London The Same Story As Culpa Mía?

When I first watched “Culpa Mía” in 2023, I was immediately hooked by its dramatic storyline about Noah, a teenager who moves in with her mom’s new billionaire husband and his son Nick. The Spanish coastline setting is gorgeous, with sunny beaches and dirt tracks for those intense racing scenes. Fast forward to 2025, and I finally watched “My Fault: London,” which takes the same basic plot but moves it to the glitzy skyscrapers and fancy homes of London.

The biggest difference I noticed between the two films is how they handle the characters. In “Culpa Mía,” Noah comes across as pretty childish, while Nick is honestly a walking red flag. The Spanish version jumps right into their attraction, making everything super intense from the start. There’s a ton of focus on how taboo their relationship is because they’re step-siblings.

But in “My Fault: London,” I found Noah much more mature and snarky in a fun way. The English Nick is still a rich bad boy who loves illegal street racing, but he’s way more protective and actually treats Noah like a person. They develop a friendship first before any romance happens, which made their connection feel more real to me. The London version barely even mentions the step-sibling thing, which was a relief.

Why My Fault: London Improves On The Original Romance

The ages are different too – in the Spanish version, Nick is 21 while Noah is 17 (yikes!), but the London remake smartly ages them to 19 and 18.

I also loved how “My Fault: London” took what worked from the original and improved on the storytelling. Since it came out two years after “Culpa Mía,” the writers clearly learned from previous criticisms. The English version focuses more on building genuine emotional connections between characters rather than just throwing in dramatic twists and steamy scenes (though don’t worry, there are still plenty of those!).

Both movies lean heavily into their cultural settings. The Spanish film has this vibrant, passionate energy that matches its coastal location, while the London version goes for a sleek, cosmopolitan vibe with underground parties and parking garage races.

While I enjoyed both films, I understand why most fans prefer “My Fault: London.” It feels more realistic in how it handles relationships, even within such a dramatic storyline. The characters have authentic personalities and motivations, making it easier to root for them despite their complicated situation.

If you’re a fan of Wattpad adaptations like “After” or “The Kissing Booth,” you’ll definitely want to add these to your watchlist. Just be prepared for some seriously steamy romance, beautiful European settings, fancy cars, and even a bit of crime thrown in – everything this basic girl loves in a good drama!
