‘Next-Generation’ K-Pop Group AtHeart Introduces 3 New Members Alongside Personal Social Accounts

Following Billboard’s exclusive announcement of TITAN CONTENT’s “next-generation” K-pop act this summer, three new members of the highly anticipated girl group AtHeart have arrived for fans to get to know.

Meet Seohyeon, 16, from Korea, Katelyn, 17, from the Philippines, and Aurora, 15, from Japan, who join the previously introduced members Sorin and Michi, helping create a diverse ensemble poised for global appeal. The five future stars join AtHeart, which TITAN says will reveal their full lineup soon before debuting in early 2025.

With talent handpicked from global auditions this past January, TITAN emphasizes members’ personalities and musical abilities while allowing fans to familiarize themselves with each member via individual social media accounts — a rarity for K-pop artists in training. @seohyeonatheart, @katelynatheart, and @auroraatheart all launched today on Instagram and TikTok.

“Over the past year, the TITAN team has seen remarkable growth, assembling an all-star group of experts across various fields,” Dom Rodriguez, CBO at TITAN CONTENT, tells Billboard. “Our commitment to delivering exceptional music, creating a new paradigm for K-pop on the global stage, and pushing the boundaries of innovation remains stronger than ever. We’re thrilled about the incredible talent of the AtHeart members and are excited to show the world what they have been working on, so stay tuned!”

In a press statement, TITAN CONTENT CEO Katie Kang highlighted the new group members’ skills and teased AtHeart’s upcoming full lineup announcement.

“We are confident that AtHeart will lead the way into a new era of K-pop,” the former SM Entertainment manager and casting recruiter said. “Seohyun stands out with her captivating vocal tone and diverse range of exceptional talents. Katelyn was cast at the Manila global audition and has vibrant energy and a bright smile that brings joy to those around her, along with her singing and rapping abilities. Aurora, with her enchanting brown eyes, is full of bright, positive, and loving energy, just as her name suggests, and incredible vocal and dance skills…the full lineup is now complete, and we’ve been gradually unveiling the members since July with the remaining members to be announced very soon.”

TITAN’s Chief Visual Officer, Guiom Lee, says the newly revealed “Second Heart of AtHeart” concept video hints at the group’s style, sound, and potential number of members, noting the “visual and playful elements that are distinct from the first concept video. And speculating about how many members will be in the group adds another layer of excitement.”

Backed by former SM Entertainment CEO Nikki Semin Han alongside a creative team of international K-pop movers and shakers, TITAN CONTENT has positioned itself as the first major U.S.-based K-pop agency, aiming to introduce multiple groups and several solo acts by 2028. AtHeart’s 2025 launch kicks off a powerful new chapter for both TITAN and the global K-pop industry.
