Cortis burst onto the scene with their pre-release single, "Go!" BigHit Music K-pop boy group Cortis is not even two months into their career - but it's nearly impossible to tell. The five-member outfit is the first boy group to debut from BigHit Music - the home to supergroups BTS and Tomorrow x Together - in six years. On their first official trip to Los Angeles as a freshly debuted group, Cortis seems to be taking everything in. The group, consisting of members Martin, James, Juhoon, Seonghyeon and Keonho, filter into the lobby of a Koreatown dance studio one-by-one, politely introducing themselves before finding a spot on nearby couches.

But once Cortis gets to talking about their music, they're transformed into seasoned professionals. Color Outside the Lines radiates youth. The group opted to forgo the concept-heavy, artistic and visual direction - instead, their pre-release single, "Go!," is chaotic and catchy. The accompanying music video also fits that mold, showing the teens galavanting around L.A. It feels like something made by teens for teens (and beyond). Mostly, because it is. Cortis is heavily involved in the creation of their own music and their artistic direction. "What You Want," the group's second song, is sonically different from "Go!" in nearly every way, trading the trap beats for a guitar and drum-heavy anthem. But both songs fit the group because Cortis seems focused on one thing more than making exactly the kind of music expected of them: Authenticity. "How do we express ourselves as raw and authentic as possible?" James asks about what he sees as the group's main goal. The 20-year-old was previously part of a well-known pre-debut group, Trainee A, and has produced songs for other artists under Korean entertainment giant Hybe, BigHit Music's parent company. "Achieving [a debut on] the chart is a nice thing," he continues. "But what really solidifies that I'm proud of my job and I like my job is performing and meeting people." Below, the boy group speaks with THR about connecting with fans in L.A., what it would mean to follow in their senior groups BTS and TXT's footsteps and why authenticity is so important to them. Can you tell me how you're feeling about a month from your debut? MARTIN Everything feels surreal. A few days ago, we went to a Red Bull dance battle as a guest. Getting invited to places and just being somewhere that I dreamed to be at is kind of crazy. It's like everything feels so surreal. JUHOON We also had a fan sign event here. There were so many people in that building. I was really shocked and also really thankful at the same time. Cortis performing at the iHeartRadio Theater during their recent L.A. trip. Anna Lee Media/iHeartMedia/BigHit Music Did you guys think that you would get to do some of this stuff as quickly as you did? Coming to L.A. and having a fan sign internationally, that's not super common. What has that been like? SEONGHYEON I honestly did not expect to get this much love and this much attention from overseas fans. Has there been anything that's surprised you the most? JUHOON For me, charting on the Billboard 200. (The group's first EP debuted at No. 15 on the Billboard 200). We did not expect that to happen. MARTIN Not at all. JUHOON With this album, we just really wanted to focus on expressing ourselves, but luckily those things happened so we're really thankful. Obviously, charting is exciting. Does finding success with this EP feel validating for you? You've been training from a very young age. Does that make it feel worth it? MARTIN It feels very worth it. And also it's like a dream come true in a certain way. I didn't even expect [to chart on] Billboard. Being on charts, topping charts.... We [hit] first place in Spotify Global Daily ... and also on the Korean Apple Music chart. Because we know how it was made, those kind of songs, being on charts and seeing people enjoy them and doing [dance] challenges, it's so surreal. At the same time, all I can do is just appreciate the fact that they enjoyed it. JUHOON Especially for me, I think performing on stage is worth it. JAMES Rather than entering a chart - I think the chart is a big achievement and I think we do have goals for our music - but I don't think it's like the chart or a certain number. I think it's more of what we feel, and what kind of feeling we get from the song. That was the main goal. How do we e
