The K-Pop world is no stranger to exciting comebacks, but rookie girl group AtHeart is taking fans on a truly special journey. With their “Time Travel Project,” they’re not just looking to the future, but brilliantly revisiting the past, bridging generations with a fresh take on a beloved 90s classic.

Rookie girl group AtHeart has reached back three decades for its latest release, remaking Roo’Ra’s 1996 summer hit “3!4!” as part of its ongoing “Time Travel Project.”
Bridging Eras: A Meaningful Mission
For the talented members of AtHeart, whose average age hovers around 18, tackling a song released long before any of them were even born presented a unique and exciting challenge. It’s a testament to their dedication and the timeless appeal of K-Pop history.
“I knew ‘3!4!’ even before we decided to remake it, and it was a song we frequently played during practice,” Bome said at a showcase in Seoul on Wednesday. “I believe the ‘Time Travel Project’ acts as a bridge connecting the past and the present. That is why it is so meaningful, and we approached the remake with a sense of mission and responsibility.”
“3!4!” holds a special place in K-Pop history, originally released by the iconic coed group Roo’Ra in 1996. It quickly became one of the mixed-gender group’s signature songs, perfectly encapsulating the upbeat, vibrant summer pop sound of the era. To ensure authenticity while bringing a modern flair, K-Pop veteran Lee Hyun-do, who originally wrote “3!4!,” even participated in arranging AtHeart’s remake – a true stamp of approval!
The intergenerational connection extends even to the members’ personal lives. Nahyun shared how her mother, a longtime devotee of Roo’Ra member Chae Rina, actively encouraged her to delve deep into the original performances.
“My mother was a huge fan of Chae Rina, so she told me, ‘Make sure you watch Chae Rina’s videos. You really need to watch and study them,'” Nahyun recounted, highlighting the deep-rooted impact of K-Pop classics across generations.
AtHeart’s Refreshing Spin on a Classic
Rather than simply recreating the original, AtHeart set out to infuse “3!4!” with their own distinct charm and youthful energy. This wasn’t just a cover; it was a reinterpretation designed to captivate both nostalgic fans and new listeners.
“Because ‘3!4!’ is such a famous song, I felt the pressure, but we tried very hard to incorporate our own refreshing vibe,” Michi said, perfectly capturing the delicate balance between honoring a classic and making it their own.

Nahyun said the differences in the groups’ size and makeup also allowed AtHeart to approach the vocals differently.
“There is a difference in our group size and composition compared to the original Roo’Ra, which brings a big change in vocals. We maximized our lovely charm in our version of ‘3!4!’ through diverse vocal combinations,” she explained, promising a unique auditory experience that showcases AtHeart’s individual strengths and collective synergy.
The group even received a special blessing from one of the original legends herself! Roo’Ra member Chae Rina met with AtHeart, offering warm words of encouragement for their bold endeavor.
“We met Chae Rina and told her we were remaking ‘3!4!,'” Seohyeon shared. “She congratulated us and warmly cheered us on, saying, ‘You must hit No. 1 on the music charts.'” Such a powerful endorsement from an industry senior speaks volumes about AtHeart’s potential and the respect they’ve garnered.
Beyond the Music: A Time-Slip Drama and Pager Discoveries
The “Time Travel Project” isn’t just about the music; it’s a multi-faceted experience. The single is brilliantly accompanied by “3+4!,” a captivating time-slip drama that sends the AtHeart members journeying between the futuristic year of 2026 and the vibrant K-Pop era of 1996. This creative concept truly brings the past-meets-present theme to life.
For these young idols, recreating the 90s era for the drama also came with some surprising discoveries, highlighting the rapid pace of technological change.
“I had used cellphones since I was born, so it was my first time ever seeing a pager,” Nahyun amusingly revealed, underscoring how deeply embedded their generation is in modern tech and the fascinating cultural differences the project brought to light.
AtHeart’s remake of “3!4!” is more than just a song; it’s a heartfelt tribute, a bridge between K-Pop’s golden age and its vibrant future. By infusing a timeless hit with their unique “lovely charm” and “refreshing vibe,” AtHeart is not only making a name for themselves but also inviting a new generation of fans to appreciate the rich legacy of K-Pop. Don’t miss out on their incredible journey back in time!
