TWS' Youngjae is lending his voice to the big screen, joining the soundtrack of Korea's beloved animation franchise The Haunted House.

On December 16, PLEDIS Entertainment announced that Youngjae will sing "Once More, Goodbye," the OST for The Haunted House 10th Anniversary Movie: Once More, Summon. The track serves as the theme song for the upcoming theatrical release.

A Fresh City Pop Sound for a Milestone Film

"Once More, Goodbye" is a city pop track built on a refreshing band sound. Rhythmic drums and bright guitar lines come together to create a breezy, uplifting mood that fits the film's tone.

Youngjae was selected as the OST vocalist early in the planning stage. The production team shared that they envisioned a fresh male voice that would match the springtime setting of the story, adding energy and emotion to the film. Youngjae's clear and youthful tone was said to perfectly align with that vision.

Through this song, the film looks back on the memories shared with The Haunted House fans over the past decade, while also sending a hopeful greeting toward the days ahead.

The Haunted House 10th Anniversary Movie: Once More, Summon follows Shinbi and Hari as they face a revived underworld threat to save the world. The film is set to hit theaters in January next year.
