He cleared out his favorite hoodies and learned how to handle Cubase with ease. While many things keep on changing, some things are forever constant: the music, the group, and MOA. They are the true passions of HUENINGKAI, whose confident tone reassures us of his commitment to forever.

You cleared out some of your hoodies and stuffed toys—what you called your “horcruxes.”
HUENINGKAI: Well, the hoodies were way too small for me anyway. (laughs) I wanted to try out some new styles, too, so I cleared them out. I decided I needed to ditch the hoodies first and try something prettier, including buying some knit sweaters. I also felt I could do away with my old stuffed dolls and replaced them with some new fluffier ones. It’s hard the first time you get rid of stuff, but I found it gets easier after that.

You’ve made a lot of big changes in different areas. You’ve been keeping up with your exercise, even throughout the ACT: PROMISE world tour, forming the TXT Exercise Team and regularly taking “TXD” [today’s exercise done] photos. (laughs)
HUENINGKAI: I always take TXD shots. I share them in our group chat. I started working out to boost my self-esteem since they say it helps, and it definitely helps keep my mind off things when all you can think about is how tiring it is! (laughs) You can’t help but lose weight if you box. It’s the only thing that makes me sweat as much as performing in concert. There’s someone on staff who’s been doing CrossFit for a long time, so I recently started too. My goal was never to bulk up and get these huge muscles in the first place but to have a slim build with lean muscles, so CrossFit seems like a good fit for me. And MOA, you don’t have to worry—I’m not going to overdo it. (laughs)

A lot of MOA were surprised the way you threw the guitar during the performance of “Growing Pain” on the ACT: PROMISE tour.
HUENINGKAI: My image sure underwent a transformation. (laughs) I wanted to show how even someone like me, who’s usually so pure and soft, has some rock star inside him. I looked up different ways of capturing the idea of smashing up the stage. I initially thought about breaking the guitar, but I figured throwing it would be better. That was all I did early on in the tour, but by the time we took it to the US, I experimented a lot, throwing the pick and flipping my bangs back later on. I was happy I got to show off a different side of myself through all that.

You’ve always had a knack for playing instruments and like playing them for fun. How do feel now that your YouTube series HUENINGKAI Wants to Start a Band is over?
HUENINGKAI: I love playing instruments and being in a band, so I was thrilled to be able to make it. Just holding an instrument in my hands makes me feel happy, and actually interacting with and jamming with a band felt like a quintessentially youthful experience. The whole thing was fun to shoot. It never felt like work to me. I approached it like I was going to hang out with a school band.

What do you think makes being in a band so uniquely appealing?
HUENINGKAI: I think it comes down to the eye contact you make while playing together. I think chemistry’s the most important part of a band, and when you’re looking each other the eye and having a good time together, you feel fully united. I feel like rock has the power to make unforgettable memories for both the band playing and their audience. I heard MOA saying they’re interested in playing in bands now or want to get back into learning an instrument. HUENINGKAI Wants to Start a Band was a huge motivation for me, and it makes me happy thinking it planted the seeds for some great dreams among MOA. I hope they challenge themselves to pursue whatever they want and achieve their goals, whether that’s playing in a band or something else. Just the act of trying something new takes a lot of courage, and if they build up some experience, they can truly enjoy their youth.

What form did that sense of youthfulness take on when you were making the show?
HUENINGKAI: It’s the kind of youthful experience you can only experience during your university years, full of excitement, sorrow, and happiness all mixed together. The song “Kitto Zutto” is actually supposed to be about how I felt filming the Yonsei University episode of HUENINGKAI Wants to Start a Band. I seem to remember working on it between filming episodes two and three. I tried to make the chord progression feel both bright and also have a refreshing, youthful vibe. The very first thing I made was the piano track, but it felt a bit bland, so I turned up the BPM and then it sounded great! The funny thing was that I tried to play at that higher BPM but my fingers couldn’t keep up. (laughs) Since it would’ve been a little bland with just the piano, I felt like it’d be nice to have a catchy melody, so I had a guitar riff repeat from the intro onward. That’s the main highlight of “Kitto Zutto.” The drums gradually build up the sound and create a sense of flow.

How do you think it compares to the first song you produced, “Dear Sputnik”?
HUENINGKAI: I’ve grown so much since then. When I was working on “Dear Sputnik,” I didn’t know how to use Cubase, but I used it to make the song this time. It was easy and convenient once I got the hang of it and got better as I used it more and more. Actually, for “Dear Sputnik,” I created the basic structure, but I got a lot of help from other people since it was less than two years since I debuted. I really wanted to contribute a greater share after that, and I did contribute significantly more to “Kitto Zutto.” It’s the first on a path of hard work towards being able to make a song I can truly call my own.

When you had just debuted and you were on Section TV, you said, “Ever since I was a trainee, my one goal has been to make and perform songs that can move people.” To what degree have you achieved your goal?
HUENINGKAI: With “Dear Sputnik,” 30%—“Kitto Zutto,” 60%. Right from when I was first writing “Kitto Zutto,” I was thinking about how fun it would be to sing it with MOA in concert. Nothing makes me feel more fulfilled than when I see MOA enjoying a song I produced. When I performed those songs in concert, I went around in front of the audience on the moving stage and could see MOA up close and personal. They all looked so happy. I’m glad I made these songs that MOA can really get into singing along with and that we can touch their hearts with. I think singing them together gives them their final touches. I want to keep making and performing songs that everyone will love and can make them feel happy when they listen to them.

In many ways, the past year has been an excellent showcase of how you’ve grown musically. You really got people talking when you were on Lee Mujin Service and when you performed “BETELGEUSE” on the Nippon TV show THE MUSIC DAY.
HUENINGKAI: I got lots of messages from people I know. (laughs) It’s the first time so many people have reached out to me like that. I was grateful but there was something indescribable about it because I feel like I’m still in the process of finding my own voice. I’ve tried singing with something more like rock vocals, and even though I don’t have difficulty hitting high notes, I’ve been thinking carefully about how to make them sound even better. I’d like to find vocals that are a little more unique to me. Obviously being a good singer is important, but I feel like sometimes that individuality is even more important.

You’ve always been a kind person, but you seem pretty strict with yourself.
HUENINGKAI: Only when I feel like I’ve perfected a skill can I say that I’ve truly made it mine. I’m sort of a worrier so I practice on my own outside normal rehearsal time. Our new single “Over The Moon” is hard. (laughs) My feeling is, if you want to dance well during live shows, it starts with singing perfectly before you ever even stand up. And when I’m performing onstage, I just think, Just do it like we practiced. I might just end up making mistakes if I try to go beyond that.

I guess “Over The Moon” would’ve been hard since it’s more about making it feel romantic than unfolding a clear sense of progression.
HUENINGKAI: It’s not a sad song, but it doesn’t exactly feel cheerful either, so I was aiming for a kind of longing middle ground. I start out singing softly to MOA, almost like a whisper, then add in a touch more of that longing in the chorus. I see “Over The Moon” as me removing the gravelly vocals from “0X1=LOVESONG (I Know I Love You)” featuring Seori and keeping it light.

When watching “Over The Moon,” it reminded me of “9 and Three Quarters (Run Away).”
HUENINGKAI: Exactly! It’s got the same ear-tapping move on the line “whisper me my name” as in “9 and Three Quarters (Run Away),” so I ended up watching our old performances for the first time in a while. My image back with “9 and Three Quarters (Run Away)” was meant to evoke the excitement of school days, while in “Over The Moon,” I tried to convey something a little more mature, like a university student.

You also came across as mature the way you led the older members in the 144th episode of TO DO X TXT, “Abandoned Stars,” even though you’re the youngest in the group.
HUENINGKAI: That’s probably the most they’ve ever needed me. (laughs) It was scary at first, but I helped them because I felt like they wouldn’t even be able to go in if it weren’t for me. And anyway, it was less scary the second time around. I guess it’s because I’m a levelheaded person. They were clinging to me so desperately I thought my clothes would come off. (laughs) That was a first. But on the inside I was actually kind of glad and thinking about how much they need me.

You also paid YEONJUN a visit when he was shooting the music video for “GGUM.”
HUENINGKAI: YEONJUN was the first one of us to do a solo project, and since I wanted to show my support and express my gratitude anyway, I brought some dakgangjeong we could eat together. (laughs) But most of all, I really wanted to learn from him. The stage presence he had as he sang from start to finish all by himself, and watching how naturally he ad-libbed towards the end, was all pretty amazing. (laughs) His solo was a good experience for us, too.

You’ve always emphasized in interviews how you want to be dependable for the rest of the group. What does trustworthiness mean to you?
HUENINGKAI: Teamwork. The greater the trust between us, the stronger our group becomes. As a member of a kind of team, it’s always my hope that the other members can continuously rely on me. That’s what being a team is, after all.

And honesty is crucial for mutual trust, of course. In an interview with W Korea, when asked what it takes for a group to last a long time, you said, “Teamwork. Being open with each other about feelings.”
HUENINGKAI: I actually never used to talk much about my feelings. I thought things would just work out over time, but now I talk things over with the people I’m close to, like the other members, my family, and the protocol team, no matter what it is. I really listen to their feedback, too. It just feels better that way. But it’s not at all easy to open up about what you’re feeling inside, of course. You can never just be like that from day one. So I just started slowly, and now I’m more open than I was last year.

You posted a letter on weverse for the fifth anniversary of your debut, and in it you talked about how you’ve always been careful to hide your feelings away because you didn’t like to talk about them. What made you decide to open up to MOA?
HUENINGKAI: I never wanted to let MOA know when I was having a hard time. I always wanted to show them the good sides only. But the longer we were together, the closer we became, and I realized that also talking about those things was the right way to further develop the relationship. That’s why I was honest and open in what I wrote on weverse on March 4. I resolved to be more honest and open from then on.

It takes a lot of courage to be open like that. How did you find it in you to find the courage?
HUENINGKAI: It’s all thanks to MOA’s love. Every time MOA opens up through their fan letters or in person, I can sense their love. The phrase, “my youth is TOMORROW X TOGETHER,” is beautiful, and hearing, “I’ll love you completely for who you are, no matter what—I love you so much,” absolutely fills me with strength. All these people around me were showing me love, but I felt like I didn’t love myself. I learned to love myself thanks to MOA.

It’s clear that you have an immense amount of love toward MOA, too, like when you said, “It may have been hard doing what it took to debut, but I could do it all again 100 times if it meant I could be with MOA.”
HUENINGKAI: I wanted to show them just how much I love them. There were a lot of times I felt like giving up before I debuted, but MOA helped me forget all about it. I know what it means to find happiness as an idol thanks to them. I think MOA is what’s made TOMORROW X TOGETHER whole.

You seem to want to hold onto the feeling of love for a long time, much like the idea of promising someone eternity in “Higher Than Heaven.” What’s someone or something you feel confident you could love forever?
HUENINGKAI: MOA, naturally. I want to send them somewhere they can be even happier than heaven, like the title “Higher Than Heaven” suggests, and where is MOA happier than at one of our concerts? I want to keep working hard to write good songs to perform for them in concert. And if MOA’s too obvious a choice, then … eggs. I really love eggs, too. (laughs)
