After their debut EP, “Plot Twist,” AtHeart is back with their latest digital single, “Shut Up,” marking a new era for the group. AtHeart is a seven-member group comprising Nahyun, Bome, Seohyeon, Arin, Michi, and Katelyn, with a focus on connecting with a global audience through their sound.
On February 24th, the group released concept photos for their digital single “Shut Up” on all social platforms. This caught everyone’s attention as it was completely different from their debut concept. Showcasing a high-fashion and direct persona of who they aim to be as they become and evolve from being a “rookie” group. Their latest digital single, “Shut Up,” focuses on a more sophisticated and bold concept. This is the first chapter of a double single comeback, with the second part, “Butterfly Doors,” set to release on March 11, 2026.
“Shut Up” is about being confident in everything you do, as actions speak louder than words. Actions are seen as more reliable in determining who a person is. The lyrics have a playful and sassy vibe. They tell the story of someone who wants actions before explanations, because it avoids over-analyzing one’s true feelings. Their youthful and energetic vocals grab a listener’s attention early, showcasing their growth as artists. With a pop R&B track, AtHeart still brings a fun idea to a fearless concept.
A music video was also released for the track, which was entirely filmed in Los Angeles. Which fits the aesthetic of the song with the diverse environments and bright colors, it brings another appeal to the comeback. The choreography is also easy to follow and highlights the focus points of the song, which was created by Harimu from 1MILLION Dance Studio and was under the direction of Lia Kim.
AtHeart is a group to watch for 2026, with their new chapters ahead of them. They are set to show their unified color as one, through their performances and activities. “Shut Up” is now available wherever you stream music.
