For his second solo ‘NCT LAB’ release, the K-pop singer reflects on his changing mindset and the trove of unfinished songs in his notes app

While many may choose to spend their birthdays giving themselves a well-earned break, Jaehyun wrote a song. “It was really sunny outside, so we had very positive thoughts in our head, and I think that’s why the mood and the vibe and the sound came out really bright and happy”, the 26-year-old NCT member says about his new single ‘Horizon’. It’s the latest song to come out under the NCT LAB project, where members of the K-pop boyband release standalone solo or unit tracks.

Like 2022’s ‘Forever Only’, his last ‘NCT LAB’ single, Jaehyun’s oaky baritone moulds to the bouncy R&B stylings of ‘Horizon’, a breezy and light song about piercing the clouds and finding the serenity above them. “I thought of horizontal moments, like when views are really calm and peaceful,” he says about ‘Horizon’, which he co-composed with regular NCT collaborator DEEZ and producer SoulFish. “The day that I mostly thought about while writing the song was a day that was really cloudy and gloomy. I was on a schedule to another place, so I rode an airplane and once I went up beyond the clouds, it was really calm and bright. And at that moment I thought that, even at the same time or in the same place, how you think is the easiest but biggest change you can make to feel different.”

There’s a sense of intentionality that runs through the core of Jaehyun, almost like the strong and stable slice of a skyline. It makes sense when you consider that his time, or sometimes the lack thereof, is such a commodity as he balances everything from music – in the shape of NCT at large, his homegroup NCT 127 and the recent debut of the sub-unit NCT DOJAEJUNG to acting to a partnership with Prada which, among other things, recently took him to Italy where he filmed the music video for ‘Horizon’. Deciding the course of his own mindset is just one of the ways that purposeful drive filters into his life.

His notes app is a precious trove of lyrics and half-songs that he tinkers with in scarce moments of downtime. He prefers to master a new craft or hobby before sharing it with the world and he approaches his own musical inspirations like a study session. “If I have an artist that I like, I like to listen to the album and then I watch some interviews. Then, if they talk about the music or the older songs that they like, then I search for those songs,” he says, continuing the cycle ad infinitum. “Then I take a look at those artists and find the artists that they like.” For those curious, the current favourites on his playlist are Kaytraminé’s debut album, Kool & The Gang and “all the ’90s.”

Even in moments that call for improvisation, like rare days without a schedule or two to tie him up, he plans his planlessness. Usually, it involves deciding not to set an alarm, even if that means waking up in the afternoon, but recently, he’s filled the blank canvas of his free days with exploring more of his own music. “I have lots of work, but when I’m composing or writing, like in the moments that I spend time in the recording room or working on a song, that’s one of the happiest and most satisfying parts of doing this job.”

2023 marks seven years since the official introduction of Jaehyun to the world, first as a part of the rotational unit NCT U with the single ‘The 7th Sense’ in April 2016, and then soon after in July with the debut of NCT 127. “That first year, the first thing that comes to my mind is our debut moment. For NCT, actually, it was in China, our first actual performance stage, and I really remember that atmosphere, the flashes of the cameras and just the crowd of people,” he says, a smile brightly hitting the tone of his words.

“And also, for 127, I remember wearing clothes that felt really young and unique, very ‘neo’. It was really ‘neo style’,” he says, referencing the maximalist styling for the group’s first single ‘Fire Truck’. “We had some long dresses over our pants, and our hair was really crazy and I remember doing this jump move with our legs up? There’s a move where we just keep jumping on the same spot.” He laughs, those seven years ago seeming much further back in time than they are.

Still, going from the final crest of teenagerdom to your mid-twenties can feel like experiencing three entirely different phases of life, especially when it comes with the pressure of work and the watchful gaze of adoring fans and a curious public. But while time has enveloped and shaped Jaehyun, he feels fairly unchanged by its current. “When I meet my school friends, they always say that I look so similar to our school days, and that my attitude and personality and my looks haven’t changed a lot. They always talk about that”, he reflects, turning the observation to be more introspective.

“But for me, I think I like the base is really the same, there’s nothing really different, but I think I got older. Lots of experiences and events happened that made me get older, but I still do feel like I’m 20 years old.” Reflecting on what he would tell his younger self given all those hardening moments of transformation, he simply says: “feel it all”. “Every up and down, feel it 100 per cent. When you feel happy, feel it 100 per cent, when you feel bad and are having a hard time, feel it 100 per cent.”

Like the horizon his sophomore solo ‘NCT LAB’ single is named after, Jaehyun’s path keeps heading out into the distance. There’s an imminent NCT comeback (which he coyly describes as “really good” after pondering over how much he can reveal) as well as a return to acting in the film You Willl Die In 6 Hours, which he just finished shooting. Before the end of the year, he also wants to go snowboarding and make progress on the surfing he learned while in LA last year with bandmates JohnnyTaeyong and Taeil: “That was my first and last time surfing. But I want to try it again because I really want to stay standing for a longer time.” Mostly, he just wants to release more music, the goods of his notes app heavy in his pocket. “I really want to share more.”

Jaehyun’s new ‘NCT LAB’ single ‘Horizon’ is out now

Unless you’ve been living in self-imposed social media exile for the past six months, there is a high probability you’ve witnessed the choreography of Simon Donnellon. Perhaps via the flirty, candy-hued video for PinkPantheress and Zara Larsson’s ultra-viral “Stateside (Remix),” or maybe in Alyssa Liu’s triumphant 2026 Winter Olympics performance set to the same song, which saw some of Donnellon’s catchiest moves repurposed for the ice. Over the past few years, the London-based choreographer and movement director has made a niche for himself, coaching a starry roster of alt-pop princesses to move unencumbered across stage, screen, and beyond. Speaking to his friend, writer and pop devotee Harald Smart, Donnellon shares his origin story and offers a window into the ‘Pop Girl Bootcamp’ that has helped more than one diva find her groove.

———

HARALD SMART: Simon, hi!

SIMON DONNELLON: Harald, hi, how are you? 

SMART: I’m good! Excited to be talking to you. There’s so much to talk about. I wanted to ask how you got started in this field, your origin story.

DONNELLON: What’s pertinent to my job now is that I was a dancer, mostly with contemporary companies, and I graduated when it was kind of in vogue for contemporary dance to be across music projects. So I was doing music videos, dancing in them, and then I got the opportunity to choreograph one for Self Esteem. Then, I started moving a bit more into artist coaching. Back then, it wasn’t such a big thing. Now, I’d say 90% of the musicians you see performing live will have had some level of movement direction or performance coaching. 

SMART: So, what’s the distinction for you between movement direction and choreography? 

DONNELLON: With choreography, I’m creating movement steps that you will learn and repeat. Direction is much more about giving people stimuli and guiding them through stuff. That could be a character-based stimulus or asking, “What color is this song?” or “What does this song smell like?” So they can start to build a world around the song to inhabit, which would hopefully give them more room to play on stage. For me personally, my job is more about setting artists up with the tools to be able to play freely on stage with a level of comfortability.  

SMART: You worked with Romy [Madley Croft] in that capacity, right? How did that process start?

DONNELLON: Yes. Romy was super interesting because I’m a huge fan of The XX. So when that opportunity came up, I was freaking out. Her wife’s a really successful photographer and director. I’d been shooting with her and she was like, “Oh, my wife is a musician and she’s doing a solo project [2023’s Mid Air] for the first time.” 

SMART:  Did you know it was Romy at the time? 

DONNELLON: I didn’t know it was Romy.

SMART: That’s so funny. 

Simon Donnellon

DONNELLON: So, when we started working together, her refrain was, “I just want to feel more confident in moving on stage.” We would get in the dance studio and I’d set up a fake DJ deck with some ballet bars and a table top across them. At first, it was really about diving into rhythm and going back to basics. Giving Romy the tools to start to move a bit freer. I think with a lot of artists, it’s about giving them permission. Because Romy can move, but I think it was just trying to give her a new movement language to use. 

SMART: It must be amazing to watch over a period of time, watching someone blossom. 

DONNELLON: Totally. And I think some people would look at one of her shows and be like, “Oh, what is the movement direction there?” because she’s just moving freely. But actually, from where she began, now she’s running around the stage at Glastonbury. In the new XX show that just debuted at Coachella, she’s singing “Enjoy Your Life” out on the runway, which is something I think she didn’t think she was capable of. She’s always been capable of it! 

SMART: That’s quite beautiful. 

Simon Donnellon

DONNELLON: I think every person, no matter whether they’re a pop star or not, deserves the space to find what it is they do free from intense scrutiny. No one’s doing the best thing they’ve ever done straight out of the gate. I mean, some people I work with are pretty incredible straight out of the gate… PinkPantheress, for example. The music and the tone of what she’s making is so unique. 

SMART: 100%. So let’s get into that. Because I feel like every day I see a fan edit or a meme or something related to PinkPantheress and her stage presence transformation. What kind of phase she was in when you started working together and how has that relationship evolved?

DONNELLON: At the very beginning, before Fancy That, we did the videos for “Picture of My Mind” and “Capable of Love,” which were more narrative.

SMART: “Capable of Love” is incredible. 

DONNELLON: I remember when I first heard that song, I kind of couldn’t believe that she’d made something that epic.

SMART: Yeah, it’s like her version of a power ballad.

Simon Donnellon

DONNELLON: Literally. And so we’d started working together a little bit sporadically and we just got on really well. From that point on, each project had a larger choreography component, especially coming back for Fancy That. I think she’d had a bit of time off and she came back and the music was so good and she was like, “I’m ready to step into it. ” Also, she can groove. She’s got a great sense of rhythm. But I feel like at Glastonbury [2025], she switched something on on show day and we were all like, “Whoa.” That was a real moment of stepping into performance in a way that she hasn’t before. I think she’s come back to this new era and attacked it with such…

SMART: Gusto?

DONNELLON: I was trying to find a synonym for gusto!

SMART: Just say it!

DONNELLON: Gusto! Like, she wants to be eating it up on stage. She wants to be involved in everything. She’s learned so quickly and I can’t take all the credit on that. I definitely got her to a certain point, but she’s also worked with super established female choreographers as well—Charissa Kroeger, Danielle Polanco, Luam, who did the 2025 US/Australia tour. And I think having that time with them, they’ve given her this new confidence. 

SMART: It sounds like a really strong team.

DONNELLON: Yeah, it’s important to Pink that there are women across choreography. Charissa is amazing. We were able to riff off each other and find this newer thing for Coachella, which is a really big, super ambitious show.

SMART: It was so impressive, the number of elements, the storytelling. 

Simon Donnellon

DONNELLON: Totally. And it’s one of those shows that is a statement of intent because she straddles all these different things. She’s the pop girl, but she’s also making this quite alt music.

SMART: It’s also so British as well!

DONNELLON: A vast majority of the team working on the show are actually British. I think that’s been a big thing for finding the nuance and the comedy and all these bits that feel “Big Pop Show,” but also still feel very her. I think one of the other big tasks for this show was finding newness in the movement language. 

SMART: How do you approach that?

DONNELLON: For me, it’s looking at other artists that sit within the same world and what they are doing. Not to copy, but thinking about what it is they’re doing that is resonating. For example, everyone thinks of Gaga like, “Put your paws up.” But Gaga also sits in this ticking world; it’s her specific way of moving. The task for the show was trying to find something that feels very unique to PinkPantheress. What are the Pink-isms? 

SMART: And what would you say those are?

DONNELLON: Always that insane hair flip. She’s in the hips, and she’s really good at finding a mix of fluidity and staccato in the upper body. It’s finding those moments, but also what is the music saying? We still want it to feel a bit punk with a tiny injection of silliness and camp. So, it’s mixing all those things together. 

SMART: What’s been your favorite song of Pink’s to choreograph? 

DONNELLON: Ooh, I mean, I love “Tonight.” For me, it has a special place. It was the first track for her that we really choreographed. 

SMART: I remember that video dropping and everyone being like, “Oh, she’s really doing the thing.” Backing dancers, the whole nine yards. 

DONNELLON: Exactly! So seeing that, editing that into the [Coachella] show and making it bigger and more exciting, that’s been really amazing. And honestly, “Stateside.”

SMART: Oh, we’re getting to her! Tell me about your involvement with that particular song and your response to where it went. 

DONNELLON: My god, crazy. With Pink, the video scheduling is always really reactive. The energy is like, “Okay, the song’s doing well, the fans want something, let’s give their fans what they want.” I had heard someone whisper that they were thinking about a video with Zara, and I was like, “Oh my god.” Then [director] Charlotte Rutherford—who I’ve worked with a lot in tandem with PinkPantheress—called me and was like, “Okay, this is the concept.” It all came together really quickly. There was essentially one day between Pink and Zara’s schedules in which they could shoot it, and the shoot definitely felt really gag on the day. Two pop stars on the precipice of stardom. They’re both doing so unbelievably well. 

SMART: And on their own terms, as well.

DONNELLON: Absolutely, I think it was so intelligent to put both of their worlds in the video and smash them together. It was so indicative of the branding power of both campaigns. Then, to choreograph something that felt really fun and kitsch. The main reference was always “Fergalicious.” 

SMART: Oh my god, I said this. The second I saw it I was like, “This is Gen-Z ‘Fergalicious.’”

DONNELLON: Yes! Even down to how it was shot because a lot of the time things are shot on Steadicam, roaming around. But Charlotte was like, “No, I want straight-on choreo.” 

SMART: Old school. 

DONNELLON: Obviously the song was having a moment, but I don’t think anyone really expected how big it was going to go. 

SMART: How did you approach the choreo? 

DONNELLON: Sometimes Pink is a fun challenge. Often my contemporary [dance] background can be really useful to avoid it leaning too far into stereotypical pop. On Stateside, my associate choreographer, Angelica Wolańska, was super helpful. It’s really helpful to ideate with a female choreographer. The work feels more rounded. With the male dancers, we wanted to stay in this really masc place but, like, a bit camp.

SMART: Metrosexual!

DONNELLON: Yes! Charlotte sent me this reference from a Madness video where they’re walking in a particular way. At first I was like, “Whoa, that’s such an off-piste ref.” But then, in the context, those off-piste moments really work. And, obviously, all the boys falling and the room shaking when Zara hits her run—

SMART: That’s so good.  

DONNELLON: But Pink is really experienced with the music video thing now. She knows her angles. She can step on set and just own it. Also, her and Zara being together, they both lifted each other up so much. It was really nice to watch. Zara had toured the night before in Stockholm, flown in that morning. We’d sent her the choreo and we ran it through with her twice and she was like, “Got it.” Just real star energy. The whole thing was such a great experience. 

SMART: It’s heartening to hear that the mutual support is so strong and genuine. 

DONNELLON: Oh my god, totally. I think we’re in an era of female stars genuinely supporting each other.

SMART: I think another key thing is they’re being cute and sexy, but it’s not two women together who are just being sexual for the male gaze. It’s for the girls who want to get cute and look cute and hang out with their friends…And the gays, of course! 

DONNELLON: Very much so.

Simon Donnellon

SMART: What’s your favorite choreo moment from the video?

DONNELLON: I love the big tableau with Pink sitting on the guys’ shoulders and Zara laying on the floor. I was thinking about Renaissance paintings…and Gentleman Prefer Blondes!

SMART: Yes! Those moments are incredible. How did it feel to see Alyssa Liu perform parts of that choreography on the ice at the Winter Olympics?

DONNELLON: Crazy, crazy, crazy. To see something you’ve done, my little pop choreo, being performed on a stage like that even for a second…Working in this profession, you’re around a lot of famous people at work. There’s certain people that I’m starstruck by for sure, but I think with most people you have a level of professionalism, like, that’s just another person. But something about that moment was like, “Wow, okay. This is kind of crazy.” 

SMART: I feel like as a choreographer or a movement director, that must be the pinnacle.

DONNELLON: Oh, it’s gag

SMART: Where do you go from there? 

DONNELLON: I’m quite excited to get back to some fashion stuff, and then this year’s festival season. And then it’s thinking about other artists on my dream board…I would die to do Rosalía!
