NCT's Jaehyun Is Blazing His Own Trail With First Solo Album J (Interview)

It's been over eight years since Jaehyun made his debut as a K-pop idol with NCT, but you couldn't tell as he Zooms in from a fluorescently lit office room in Seoul. As soon as the call connects, he's giddy with excitement and ready to talk about his freshly released debut solo album.

He might have been born on Valentine's Day, but August seems to be a preordained month for Jaehyun — at least musically speaking. In August 2022, he gave fans the first proper taste as a soloist with self-penned single “Forever Only.” In August 2023, he followed suit with "Horizon," adding composition into the mix. Now, in August 2024, J - The 1st Album, his first solo project, is finally closing off the summer trifecta.

Jaehyun started crafting his solo refuge away from the green lights of Neo City brick by brick throughout the years, relishing in simplicity and pared-down visuals rather than in the rocambolesque maximalism the group has fans accustomed to. Balancing hats as a Prada ambassador, a permanent member of NCT 127, one-third of sub-unit DoJaeJung, and now a solo act, time is of the essence for Jaehyun. Taking his time with this project, however, was perhaps the smartest chess move by the star. You only debut as a soloist once.

Across its painfully short but well-paced eight-song tracklist, Jaehyun conjures up a groovy vision in J with R&B as its main conductor. Oscillating between raspy tenor vocals and honeyed falsettos, he goes from the steamy title track "Smoke," which is also featured in a full-English version, to tantalizing breakup anthems ("Roses"), unapologetically silly musings ("Flamin' Hot Lemon)," misty piano ballads ("Completely"), and jazz-synths and trumpet riffs in closer "Can't Get You," which was composed and co-written by R&B legend Kenneth "Babyface" Edmonds.

One day after the release of J, Teen Vogue caught up with Jaehyun to chat about the process of working on the album, juggling multiple personas, and his hopes for the future. Catch the full interview below.

Teen Vogue: It's been a little bit more than 24 hours since J came out. How are you feeling?

Jaehyun: I'm just enjoying the moment. I was kind of nervous on the day that I was releasing the album yesterday, but today I'm enjoying watching all the love and the support of my fans, and also watching the film, the promotion, and the contents of the album coming out.

TV: Part one of your mini-documentary, The Journey of ‘J,’ already shows you've been preparing for this for a while. Can you tell me a little bit more about the whole process?

Jaehyun: Well, as I mentioned in the short documentary, music [has been] with me since I was young. [In] my school life, I loved singing in festivals. [That's when] I started not making music but jamming with my school friends who play instruments and make music. I used to just mumble or do random melodies while my friends were doing instruments, or I would play that kind of way with my friends. And I started to prepare this album last year, [in] December. That's when this album [journey] started.

TV: In the doc, you also mention you had roughly 30 songs when you began the journey. How do you go about selecting the seven, or I guess eight, that ended up making the final cut? I know a lot of people wanted to get “Lost,” the solo song you performed on tour…

Jaehyun: Yeah. [Smiles.] Hopefully, I can bring out some of the songs that I did before, which I might be embarrassed about when they come out, or they might be really pure. I don't know if it would come out or not. But [for] these eight tracks, we had lots of meetings with the A&Rs in my label. For each and every track, I really wanted to have a reason why it's in the first album. I had a different concept and image of each track for this album, and I really wanted to make it feel classic so you could listen to it later on. That was the thought.

TV: Are there any songs that didn't make the cut that you're kind of sad about?

Jaehyun: Sad about? Yeah, of course, there are, but I guess there's a reason for these eight tracks. Yeah… But maybe later on, I could release some [of those.]

TV: You named the album J because you have a habit of marking your belongings with a “J.” When did you start doing that, and when did the idea of adapting it for the album name get to you?

Jaehyun: It was like a second. [Snaps fingers.] You usually use the title track's name for the album, so “Smoke” would be the one, but I really wanted my fans, or the people who listen to the album, to listen to the other tracks too. “Smoke” is really good. I love “Smoke,” but also the other tracks have their own messages, so that's why I didn't want to do Smoke. And J just popped up in the second, and because it's my first album, I didn't want to think too deep. I just wanted to keep it easy.

TV: I mean, it is kind of deep if you think about it as an extension of yourself, something you own.

Jaehyun: Yeah. [Smiles.]

TV: You said that this is the album you feel represents you the most. As a solo artist, you had also put out “Forever Only” and “Horizon.” Do you feel J is a continuation of those two songs or more of a reintroduction of yourself as a solo artist?

Jaehyun: I think it's all me. What I'm into at that moment, I guess that [ends up represented in the songs.] For “Forever Only,” I worked on the lyrics, and for “Horizon,” I worked on both composing and writing. On this album, I have some tracks that I worked on, that I composed or wrote, but also some tracks that I got from the writers — lovely tracks, too — so J is more of expressing what I feel would fit me right now [artistically.]

TV: Since you say you're really influenced by what you are feeling at the moment. When you were working on this album, what do you think were the biggest influences or inspirations?

Jaehyun: Wow. Each track is really different. For example, for “Dandelion,” while participating in the lyrics, I looked back at the photos that I had on my phone. I used to take photos of dandelions that were randomly on a road. “Roses” was written, like, two years ago, I guess. “Smoke” was a recent vibe that I thought was really interesting, and “Can't Get You” was [inspired by] the oldies that I used to listen to. So it's all different.

TV: The songs are all kind of R&B-adjacent, but they have a very different vibe from each other. Why do you think you gravitate towards R&B more than any other genre? And are there any other genres that you would like to try out in the future?

Jaehyun: Well, I really listen to a bunch of songs, from old soul music to pop and PC pop, which I've been really into recently. I listen to a bunch of songs, so I don't really think of one genre while I'm making music with my crew. Whenever I'm writing for something, I just want it to be me. Every single thing that I'm influenced by or have been influenced by, I guess that that comes out.

TV: J is your solo debut, but you're also part of NCT 127 and DoJaeJung. Do you feel like you are any different when you're part of different projects?

Jaehyun: I think it's all me. It's all me. But for example, when we did Walk for NCT 127, we actually had a vote for a [title] track, and [our opinions were] all different. Every member has a different taste. But I put myself in a role [to see] where it could fit as [an outsider.] So I watch it as a whole picture. For DoJaeJung, we also had some tracks that were Jungwoo's favorites, Doyoung's favorites, or my favorites. But while recording or performing, I put my 100% into what works. It's all related to myself, but for the solo album, it is more like I could see right away what I'm into.

TV: So it's more of a part of your soul, in a way?

Jaehyun: Mm-hmm.

TV: If you had to pick just one memory from working on this album, which one would you keep? Like, say you're going to lose all your memories when you're old; which one is it?

Jaehyun: Wow [Covers face with hand.] I'll choose two. One is the last year, in December, when I started this album, and I brought three tracks that I had made before and had a meeting with the A&Rs with my label. That's where it all started. And the second memory that I want to take is while filming “Smoke,” having all the... What do you call it?

TV: The syrup?

Jaehyun: Yeah. Yeah. [Laughs.] That was crazy.

TV: I saw the behind-the-scenes of that today, and it looked… uncomfortable.

Jaehyun: I felt like I was born again; after pouring all that on my face and my body, I was like, "Wow, I'm feeling new."

TV: Like a placenta type of vibe?

Jaehyun: [Laughs.] It was crazy.

TV: Speaking of the “Smoke” music video, it's pretty deep. You went for the Greek myth of Narcissus as inspiration. Why did you pick that for the visual concept? Because I guess it doesn't really translate lyrically…

Jaehyun: Well, first of all, I really didn't want the video to be predictable for the song. That was my first thought. But after I met the director of the “Smoke” film, she had a vision of the track where the lover is going to be myself, the person in the song is going to be myself. So it was a shift for me because it was interesting, too. I thought that it shouldn't be predictable, but that shift was interesting. I loved that theme and working on filming.

TV: Were you familiar with the myth at all before filming the music video? Or did you learn after getting the idea?

Jaehyun: Yeah, I searched a lot. I searched about that famous story of Narcissus. That character is very interesting, and it feels new. I felt that every person could have a moment where they feel like if someone's watching you, like you think about that someone's watching you, and what would the person think about? What would their thoughts be? Everyone might have a moment where they had that thought. So I thought it was interesting [that] I could really be another character that might be what you've thought of.

TV: Before the video came out, you posted the meme of SpongeBob ascending while listening to music.

Jaehyun: Yes. [Nods.]

TV: Was that a teaser for the video, or was this just how you generally feel about the album?

Jaehyun: It's a picture that I had on my phone for years, but I felt it was the right moment to post it. [Smiles.] It's like a spoiler for “Smoke,” but also, I really wanted my fans or the listeners to feel like that while listening to the album. So it was kind of both. It had both meanings.

TV: I like that. I like that your social media presence is a mix of super high fashion and unfiltered moments, kind of like that meme.

Jaehyun: Yes.

TV: And I feel like something related that fans really like about you is your photocards, and for this album, you really went the extra mile. Do you have a favorite photocard from J?

Jaehyun: Wow. Favorite photocard? You know what? We take tons of selfies for photocards. And… [Laughs.] I do my best every time, but I guess it's getting better and better. So, hopefully, the photocards that recently came out are going to be the best. [Smiles.]

TV: Do you get to pick the ones that ultimately become photocards?

Jaehyun: No. I just try my best selfie and just give it all.

TV: Your team has your back because they're really on brand.

Jaehyun: I believe them.

TV: In the photos you did for the album, you have little small Easter eggs for fans. You have a can of peaches, which is your emoji. I think you're also wearing your own jacket in one of the jacket shoots. Why did you want to include those Easter eggs?

Jaehyun: Wow. It's interesting how you mentioned that photo, because the concept of the jacket with that outfit was like a paparazzi film where I just walk in the streets and I'm myself. So, that concept had to be one of the outfits that I used to wear. Also, on our label, the people actually mentioned that photo on my Instagram and said, "This outfit would really fit the concept that was..." I was really [flattered.] [Smiles.] They're all good at fashion, and everyone knows them well, but they like my fashion? I was really glad and also excited to film with that one. I had three different concepts for the album jacket, but that was one I [really] liked.

TV: Second-to-last question. You said this at the beginning of the interview, and you've also said on social media: You want this to be an album that people listen to for a long time. In your opinion, what makes a timeless album?

Jaehyun: Wow, timeless. Timeless is actually a theme that I'm into these days. I guess the memories are timeless. So it could be the moment that you're listening to a song, where you are, or who you're with; that memory could be timeless. So, after years, if you listen to one of the tracks of my album, you can still feel the memory or relate to it. I guess that's timeless.

TV: Last question: What comes after J? Are you on to the next thing already, or are you relishing the glory of the project for a little bit?

Jaehyun: Well, after J comes A-E-H-Y-U-N. [Laughs.] For now, I guess I have to finish [the album promo] and do well on this album. I have lots of promotional films and content coming out. I hope my fans really enjoy and get to know more, even more, about myself. Also, I'd love for the new listeners to be interested in my voice or my style. So yeah, for now, that's it: Doing well on this album and keep on going for the new journey.

TV: I think that's a good thing to do, especially for things that have taken so long to come to fruition.

Jaehyun: Yes. And what I really wanted to say is... Well, I will definitely be doing what I do with NCT, but it feels like a new start for me, too. So I really want my fans and the people to feel like it's going to be a start and there's more to come up later on.

TV: It does feel like a start, so I think you're on the right track.

Jaehyun: Thank you!
