Rising K-pop girl group AtHeart has officially announced their highly anticipated summer comeback, confirming the release of their upcoming second single titled “3! 4!”.
On August 4, 2026, the group’s agency, Titan Content, released promotional teaser graphics across their official global social media platforms, officially initiating the countdown to the new release.
According to the official timetable provided by Titan Content, the single and its accompanying music video will be released worldwide on August 19, 2026, at 6:00 PM KST.
This strategic mid-August release aims to capture the late-summer musical momentum and further expand AtHeart’s growing presence within the international K-pop landscape.
The upcoming track serves as a landmark moment for the seven-member ensemble, which consists of Michi, Arin, Katelyn, Bome, Seohyeon, Aurora, and Nahyun.
Founded as the flagship girl group under Titan Content- an international K-pop company launched by former SM Entertainment CEO Han Se-min- AtHeart has systematically built a distinct sonic identity rooted in reinterpreting iconic pop and dance classics for a contemporary global audience.
Reinterpreting a Classic: The Significance of “3! 4!” and the Time Travel Project
The new single “3! 4!” represents the latest chapter in AtHeart’s ambitious “Time Travel Project.”
Under this creative initiative, the group reinterprets and modernizes legendary music releases from the mid-1990s, bridging classic pop nostalgia with dynamic 5th-generation K-pop production.
The song itself is a direct remake and reinterpretation of the iconic 1996 hit “3! 4!”, originally performed by the pioneer co-ed Korean dance and hip-hop group Roo’ra.
During the original era of 1996, Roo’ra’s “3! 4!” became a defining anthem of summer in South Korea, widely celebrated for its infectious rhythm, uplifting brass hook, and catchy vocal melodies.
By taking on this celebrated track, AtHeart intends to bring the vibrant energy of 90s K-pop to a brand-new generation of listeners across the globe.
This release follows the group’s previous single, “Say It”, which gained significant attention for its clever interpolation of Swedish pop rock band The Cardigans’ 1996 global smash hit “Lovefool”.
Reflecting on the group’s ongoing creative direction, a representative from Titan Content shared:
“Through the Time Travel Project, AtHeart is dedicated to honoring the golden eras of both global pop and original Korean dance music.
With ‘3! 4!’, the members aim to demonstrate their musical versatility while delivering a refreshing, vibrant energy tailored specifically for the summer season.”
By pairing international pop influences like “Lovefool” with seminal Korean classics like “3! 4!”, AtHeart’s Time Travel Project establishes a bridge between Eastern and Western musical history, showcasing how foundational pop elements from 1996 can be adapted into modern, high-energy pop performances.
Full Group Momentum and Recent Activities Leading Up to the Release
The announcement of “3! 4!” comes at a pivotal moment for AtHeart, as the group recently completed a busy schedule of domestic and international promotional activities.
Fans- officially known by the fandom name “heartbeat”- have expressed immense enthusiasm for the comeback, particularly following the full-group reunion of all seven members.
Prior to this comeback cycle, member Aurora had briefly taken a temporary health hiatus to focus on her recovery.
Her complete return during the previous “Say It” promotional period marked a major turning point for the group, allowing AtHeart to perform as a complete seven-member formation across broadcast music shows, international media showcases, and fan events.
Reflecting on their journey and connection with fans during a recent media appearance, member Seohyeon noted:
“Connecting each other’s hearts and creating a new world with our fans is at the core of everything we do as AtHeart.
Standing together on stage as seven members gives us incredible energy, and we are so excited to show everyone a new side of ourselves with this comeback.”
Since their pre-release debut activities with tracks like “Good Girl (AtHeart)”, which rapidly accumulated millions of views across global video platforms, AtHeart has drawn substantial international attention.
Major media outlets, including Billboard, Teen Vogue, and Variety, have highlighted the group’s multicultural appeal and diverse member backgrounds, noting their potential to become key figures among 5th-generation K-pop acts.
With the release of “3! 4!” set for August 19, 2026, at 6:00 PM KST, AtHeart is slated to kick off an extensive series of promotional activities, including music show appearances, concept photo reveals, music video teasers, and interactive content designed to engage fans worldwide.
As Titan Content continues to roll out promotional materials leading up to the release date, expectation remains high for how AtHeart will transform Roo’ra’s timeless 1996 classic into a modern summer smash.
