The steamy new young adult romance that's about to become the internet's latest obsession.

If you're scrolling through Prime Video this week, you might spot a steamy new romance called My Fault: London.

This isn't your average young adult romance — it's an English remake of a Spanish film that took over the internet in 2023.

The original Spanish film, Culpa Mía (which translates to "My Fault"), started as a Wattpad story — just like After and The Kissing Booth. Written by Mercedes Ron, the story became so popular it got turned into a bestselling book trilogy Culpables, which then became a record-breaking Spanish film.

And when we say record-breaking, we mean it. Culpa Mía dominated Prime Video, becoming their most-watched international original film ever. Now, the story continues with its English adaptation, My Fault: London.

Okay, buckle up.

Meet Noah, a teenager whose life gets turned upside down when her mum Ella announces they're leaving Florida for a fresh start in London. The reason? Ella's new husband, William, comes with a ready-made family including his son, Nick.

Now, this is where things get complicated (and steamy). From the moment Noah and Nick lock eyes, there's an undeniable spark — the kind that absolutely shouldn't exist between step-siblings but, well, here we are.

Think The Brady Bunch meets After, but make it British.

While Noah tries to navigate her new life in London — making friends with Nick's social circle and moving on from her cheating boyfriend back in the States — she becomes increasingly drawn to Nick, who is a 'bad boy' that enjoys partying, fighting, and racing fast cars. (Let's be honest, he's a walking red flag, but that's half the fun of these movies, right?)

Things get even more intense when Noah's abusive father gets released from prison, and he's not just keeping tabs on her — he's full-on stalking her every move. Big yikes.

So, being the film detective I am, I watched both My Fault: London and Culpia Mia… for research purposes. And I was pleasantly surprised at how fresh the new adaptation felt, despite following a very similar plot progression.

Speaking to Mamamia about their upcoming film, Asha Banks and Matthew Broome, who play Noah and Nick, explained their decision to deliberately avoid watching Culpa Mía until after filming wrapped.

"When you watch someone else play a character, it's sometimes easy to get in your head about it. You want to have a fresh mind when you approach something," Broome said.

Banks agreed: "I purposely didn't watch the film because I knew that I would get in my head and I didn't want to start imitating the amazing job that Nicola obviously had done."

In fact, the two leads watched Culpa Mia together after wrapping My Fault: London, and I kind of love that titbit.

"It was fun to see the differences, and it was exciting by the end of it to be able to see them both together," Banks said.

Look, this story is basically a BookTok fever dream come to life, serving up all the tropes we love to love (or hate). We're talking enemies-to-lovers and palpable will-they-won't-they tension that makes it, overall, a very fun watch. And as much as people love to hate these Wattpad-turned-movie adaptations, honestly, I see the appeal.

Is it predictable? Yes. Are there some overstuffed subplots that can get a little confusing? Also, yes.

But the film delivers what you go in expecting... a chaotic time with a side of spice. And that's okay.

The downsides? Let's talk about pacing because... whew. This movie comes at you so fast, I think I got whiplash. Just when you're settling in for some steamy step-sibling tension, the film throws approximately 47 other plot lines at your face.

From Noah's stalker father trying to kidnap her to Nick's backstory with his mother and his sister, plus a bunch of crazy car chase scenes and fight sequences, it can feel a little overwhelming at times. I personally would have loved a little more time to develop the relationship between Nick and Noah in the first act.

But… I will say, once the romance kicks off, it all kind of makes sense. What stood out most was the impeccable chemistry between the two leads. The casting gets an A+ from me, because... I mean, what an attractive pair of step-siblings. The dynamic between them is electric, and you really feel their connection instantly.

According to Banks, the chemistry developed completely organically from her first meeting with Broome.

"I think we're very lucky that we're just quite similar. We met and instantly got on so well. I remember meeting Matthew and just being like, 'Oh, he's just like all my friends,'" Banks told Mamamia about their first interaction.

I do have to be honest — personally, the step-siblings trope isn't one I love. In fact, I still find the whole thing a little bit icky. But if there were ever two actors who could somehow make it bearable, it's Banks and Broome. And there is something to be said about the allure of a forbidden romance that modern audiences seem to eat up.

"The trope of forbidden love is so apparent in so many things that we see," Banks explained. "Cruel intentions from way back is one of the big versions of that. And people love to hate it. It's controversial. But I think it's kind of addictive to watch, which is why I suppose people love it so much."

Now, I can't talk about this film without mentioning one very important inclusion I noticed: consent.

In a genre that hasn't always gotten this right (looking at you, basically every teen movie from the '90s), My Fault: London shows exactly how consent should look — both the verbal and non-verbal kind. And considering this film is going to be all over Gen Z's TikTok For You pages, that's actually huge.

There are several scenes where the characters actively check in with each other, and it's honestly very refreshing to see.

While on set, the portrayal of consent on screen was a huge topic amongst the cast and crew, with both Banks and Broome emphasising the importance placed on getting it right and "playing with the power dynamic" between the two leads to provide a healthy balance.

"We have an intimacy coordinator who was absolutely amazing," Banks said.

"She was so specific about having both the verbal and physical consent, because often the physical is not shown as much in film and TV, and she really was adamant that we had that and our amazing directors Danny and Charlotte were super on board. So the whole team was just amazing."

Look, let's be real here — My Fault: London isn't going to be making any Oscar acceptance speeches. It's not trying to make a profound artistic statement. What it is, though, is exactly what it says on the tin: a deliciously dramatic, steamy romance that's just a bit of fun.
