AtHeart is returning with a sharper, more confident teen-crush energy.

On February 23, the group released trailers for their upcoming digital singles "Shut Up" and "Butterfly Doors" via YouTube, previewing a noticeably more mature concept.

A New Chapter in LA

In the trailer, the members stride confidently through the streets of Los Angeles, marking the beginning of a new chapter. Their fearless steps and intense gazes highlight a stronger presence compared to previous promotions.

Dressed in striking black-and-red outfits, AtHeart amplifies their chic and powerful image. Members Michi and Arin drew particular attention with bold short hair transformations, reinforcing the group's refreshed visual direction.

Reinforcing Identity Through Storytelling

With this comeback, AtHeart aims to solidify their distinct musical color. The two releases are expected to unfold as part of an organically connected narrative, strengthening the group's evolving identity.

AtHeart will release "Shut Up" on major streaming platforms at 6 p.m. on February 26, followed by "Butterfly Doors" at 6 p.m. on March 11.
