“When people hear this song they will all be very surprised,” says Lily. “At the beginning, you think it will be one sort of song but then all of a sudden in the middle it changes into something that you wouldn’t even imagine. I feel like it would definitely pique a lot of people’s interests.”

And it definitely has: since its release, the official music video for O.O has been viewed over 71 million times on YouTube, while dance performances by the group have tens of millions of views as well, with the septet’s confidence and charisma shining as they perform complex choreography.

It is more or less intentional that people are drawn to watching the group perform O.O as much as listening to them sing it: NMIXX is a group you’re supposed to keep an eye on, literally.

“When I think of NMIXX, I think of performance. Our powerful performances on stage, where we can show our dancing, singing and charms,” says Lily.

Backstage at KCON Premiere in Chicago on May 20, Kyujin, Lily, Haewon, Sullyoon, Jinni, Bae and Jiwoo were radiating both anticipation and nervous energy before their first overseas performance. They answer our questions in Korean and English, laughing and cheering one another on, and the tension is almost tangible. They are aware that many eyes are on them.

“Because we’re receiving so much attention, we’ll work hard, and I’ll do my best to return [our fans’] love,” says Jinni.

Having spent much of their formative days training, and debuted during the global pandemic, NMIXX have only in recent months begun performing in front of live audiences and finally got to meet their fans, collectively known as “NSWER”, in person.

“Ever since we were trainees, we’ve waited for this moment,” says Lily. “I hope they’ll be really happy [with our performances] since we really worked hard, showing them a lot of different concepts and new versions of ourselves.”

They have trained hard, some upwards of five years, which is a sizeable portion of their life for these teens (Lily, the eldest, is 19, while the youngest, Kyujin, is 15 years old.)

“O.O is the first step, because it’s the first time we’re showing NMIXX to the audience,” says Jiwoo.

The intensity of O.O and Tank, both released on their first single album Ad Mare, sets the group apart in that they’re a bit harder hitting than the more typical pop or R&B on JYP girl group debut songs. The music is edgier, with hip hop and rock infusions front and centre.

“As trainees, we looked up to our sunbaenim [senior artists], and now it’s an honour to say that we can be part of that and call ourselves JYP artists,” says Lily with a smile. “I will be very happy if a lot of people, a lot of diverse people from all over the world, can come to NMIXX for solace and can come together and be happy when they listen to our music.”

Bae says: “I’m happy to debut in a JYP girl group, and I’ll do my best to be like a JYP artist. I’d love to be with my NSWER forever.”

While it’s early days and premature to truly declare NMIXX as one sort or another of a girl group, they have high hopes and dreams.

“I want to fill up people’s lives with our songs,” says Haewon. “The more [people], the better. To me, NMIXX is like a birthday present in that it’s meaningful, something to look forward to, and it gives me happiness. NMIXX forever!”
