Girl group At Heart is captivating major Korean music broadcasts with a stage reworking Roo Ra's mega-hit song '3!4!'.

At Heart appeared on MBC's 'Show! Music Core' and unveiled the comeback stage for their second single '3!4!' as part of their Time Travel project.

On this day, the members appeared in Y2K outfits combining white and pink, showcasing energetic group choreography and lively expressions set to a light new jack swing-based sound. In particular, the pair choreography and the dance break by Arin and Kaitlyn added to the immersive quality of the stage.

'3!4!' is a reinterpretation of Roo Ra's original song, released in 1996, with At Heart's own sophisticated sensibility. While preserving the charm of the original, the track adds a trendy color and has been well received, with the music video surpassing 2.4 million views amid enthusiastic attention from fans at home and abroad.

The Time Travel project is a global initiative reinterpreting hit songs from 30 years ago in At Heart's own style. At Heart plans to continue their activities through music broadcasts and various web content.
