SAMG Entertainment Taps NCT WISH’s Jaehee and Hearts2Hearts’ Yuha for “Teenieping: Legend of the Whale Heartstone” Soundtrack, Unveils Teaser Trailer

SAMG Entertainment (CEO Suhoon Kim), the Global IP content company, has unveiled the first teaser trailer for its upcoming animated feature ‘Teenieping: Legend of the Whale Heartstone and announced that NCT WISH’s Jaehee and Hearts2Hearts’ Yuha will perform the film’s first special soundtrack single.

The collaboration is one of the first major projects to emerge from the strategic partnership established between SAMG Entertainment and SM Entertainment last year. Through the combination of animation storytelling and music content, the companies aim to expand the reach of the franchise and create new audience touchpoints across multiple content formats.

Jaehee and Yuha will perform the duet track “Open Your Eyes”, which reflects the emotions of Romi and Kite as they encounter a new world and discover the courage to move forward. The song was produced by music director Taeho Kim, who has been behind some of the most recognizable music from the Teenieping franchise.

Teenieping: Legend of the Whale Heartstone is the sequel to 2024’s “Heartsping: Teenieping of Love”, which drew more than 1.24 million admissions in Korea and became one of the country’s highest-grossing animated features. The new installment follows Romi and Heartsping on a fantasy adventure to rescue Romi’s mother after she disappears into the sea, expanding the franchise’s world and emotional storytelling.

The newly released teaser trailer introduces a new story centered on a legendary whale and a mysterious curse. Alongside Romi and Heartsping’s journey beyond the Emotion Kingdom and into the open sea, the trailer previews several new characters, including Kite, a sea boy who joins Romi’s adventure.

The soundtrack collaboration follows the first film’s music campaign, which featured aespa’s Winter. With Jaehee and Yuha representing a new generation of SM Entertainment artists, the project is expected to draw interest from both family audiences and younger K-pop fans.

“Through collaborations between animation IP and K-pop artists, we aim to deliver the film’s emotional story and world to a broader audience,” a SAMG Entertainment representative said. “We will continue to unveil additional artist collaborations in the lead-up to the film’s release.”

Teenieping: Legend of the Whale Heartstone opens in South Korean theaters on Aug. 5.
