What happens when one of Korea’s most talented young actors takes his first official step into music? Can a low, soulful voice impart the same emotional heft as his popular dramas?
And what sparks fly when the actor works with successful singer-songwriter Roy Kim?
The answer comes on September 6, 2025, when Choo Young-woo officially makes his music debut with a digital single called “If Time Had Stopped“, paired with his new Asia fan meeting tour “Who (is) Choo?” starting in Seoul. For fans, it’s not only a new song, but the moment an actor they love on screen walks toward a new stage as a singer.
A Milestone Single: “If Time Had Stopped”
Choo Young-woo’s first digital single will be released on September 6th at 6 PM (KST), across all major music platforms. This will be his first-ever song with his name attached to it, making it a very meaningful project, and also a gift for the fans who have already supported the beginning of his journey.
Recorded and written by Roy Kim, known for some of Korea’s favorite ballads, the song’s warm sensibility fits Choo Young-woo’s low-pitched vocal tone nicely to create an emotional ballad we hope listeners will easily connect with.
To top it off, Choo will be performing “If Time Had Stopped” live for the very first time at his sold-out Seoul fan meeting, making it an unforgettable experience for fans to see Choo perform this song for the first time.
A Special Collaboration with Roy Kim
The relationship between Choo Young-woo and Roy Kim was built on respect. Earlier this year, Choo grabbed fan’s attention by performing an emotional cover of Roy Kim’s “Spring Comes” during his promotional activities for the drama Trauma Center. The performance went viral and then, to everyone’s surprise, Roy Kim even commented on the cover. This moment left fans wondering if we would one day witness the two artists collaborate.
Here we are. Roy Kim not only composed and wrote “If Time Had Stopped”, but also contributed to its emotional build. Many in the community are calling the Choo Young-woo and Roy Kim pairing a “dream collaboration” and its easy to see why. The relationship between Roy Kim’s warmth in his lyrics combined with Choo’s soulful performance should make for an incredible final product.
Choo Young-woo’s Musical Journey
While this marks his official debut single, Choo is not new to music. His voice has already made quite a mark via drama OSTs, such as “Oasis (Acoustic)” for Oasis, “Let’s Never Part Again” for Madam Ok Story, and “Goodbye” for Gyeonwoo and the Fairy.
In each one, he was able to deliver the characters’ feelings through song, which made fans and critics alike compliment him on his emotionality and narrative singing style. He has built a solid base to go from an actor who sings to just messenger artist with these OST performances.
Asia Fan Meeting Tour: “Who (is) Choo?”
Choo’s music debut coincides with his first Asia fan meeting tour, aptly named “Who (is) Choo?” and gives fans a chance to see who this rising star really is.
The tour will begin September 6 at the KBS Arena in Seoul at 5 PM KST, with tickets selling out almost immediately, which demonstrates Choo’s quick acceleration of popularity. After Seoul, the tour will move to international destinations, with fan meeting locations confirmed in Bangkok, Taipei, Osaka, and Tokyo.
Choo has personally organized many of the fan meeting components. From games and interactive elements, to music stages, attendees will have a personal and unique experience. There is also a play on Choo’s fandom name “Hoo Choo” in the naming of the tour, emphasizing the closeness between artist and audience.
Rising Popularity as an Actor
Choo Young-woo was a budding actor in Korea until he became a music star. He had already shown his marketability as a lead actor, starring in The Tale of Lady Ok, The Trauma Code, Head Over Heels, Oasis, and Gyeonwoo and the Fairy.
In particular, Gyeonwoo and the Fairy maintained the number one rating in its time slot, marking Young-woo as one of the leading men in Korea. He is known for his full commitment to characters, and in particular for carrying complex emotional journeys, making him a fan favorite. And now, those qualities are expected to come forward in his music career.
Expectations & Buzz
With a debut single and Asia tour launching simultaneously, expectations of Choo Young-woo are on the rise. Fans are waiting to see how he grows out of his music persona after the original soundtracks (OST), and as he balances being both an actor and singer.
The netizens are already wondering if he will do any more music projects in the future. Many feel his storytelling ability is a talent all of its own that shines.
