Hongjoong’s Hallucination Debut Turns Jeonju Into a Real Career Pivot

Hongjoong of ATEEZ has officially added film music director to his resume after debuting with the indie feature Hallucination at the Jeonju International Film Festival, a move confirmed by KQ Entertainment in reporting published by Korea JoongAng Daily on May 8. The screening took place on May 7, and StarNews reported that Hongjoong also attended the audience Q&A, known in Korea as a GV, at CGV Jeonju right after the film showed. That matters because this was not a casual soundtrack placement or a one-song sync. Hongjoong produced two tracks for the project, “Bleeding Light” and “Nothing Left,” and also contributed vocals to the latter, according to Korea JoongAng Daily. For an idol already taken seriously as a writer and producer, this is the kind of sideways creative move that can open a very different long-term lane.

The timing is sharp too. Instead of attaching himself to a glossy streaming project, Hongjoong used Jeonju International Film Festival, one of Korea’s most credible indie-film rooms, as the place to make the jump. We have already seen him build a public identity beyond the standard comeback cycle through projects like his World Vision ambassador role, but this credit feels more structurally important. It puts his production work inside a film context where mood, narrative pacing, and emotional restraint matter more than stage impact. That is a very different test from building a title track. It also lands at a moment when fans and industry watchers are paying closer attention to which fourth-generation idols can actually translate authorship into other mediums, not just talk about being creatively involved.

Hongjoong did not just lend his name. He built part of the film’s emotional architecture.

Hallucination is centered on the relationship between a human fashion editor and an AI system named Call, according to Korea JoongAng Daily, which makes Hongjoong’s role feel unusually aligned with the material. The outlet reported that “Bleeding Light” tracks the editor’s feelings toward Call, while “Nothing Left” is built around the deeper discomfort of intimacy between humans and technology. StarNews added that Hongjoong introduced the music himself during the post-screening audience session, which is exactly the kind of detail that separates a headline cameo from real creative labor. If the film is exploring blurred boundaries between personhood and machine logic, then handing that emotional tension to an idol-producer who already works with atmosphere, texture, and concept control makes real sense. This is where the story gets more interesting than standard fandom applause. Hongjoong was not there to decorate an indie film. He was there to help score its thesis.

Jeonju is the right festival for this kind of pivot

Jeonju matters here because it is not read as a celebrity vanity stop. StarNews described the festival as a space for alternative trends, independent films, and work at the front edge of artistic cinema, which is why the setting instantly gives Hongjoong’s credit more weight. A K-pop idol showing up in that ecosystem says something different from an idol appearing on an OST list for a mainstream drama. It says he is testing his instincts in a room that values craft and authorship. That broader Korean festival ecosystem has also become easier for international readers to track, with outlets like JoySauce’s look at Busan International Film Festival framing how major Korean festivals function as both industry engines and public culture events. Jeonju operates in a different lane from Busan, but the larger point holds. These are spaces where cultural credibility still gets built the hard way.

This could be the start of Hongjoong’s post-idol creative map

Hongjoong’s film-music debut does not suddenly move him out of ATEEZ territory, and it does not need to. What it does is sharpen the case that his creative ceiling is bigger than group promotion alone. HITKULTR has already covered how ATEEZ turned commercial scale into real chart weight, but the more durable story might be how key members keep building specialist identities around that success. For Hongjoong, the strongest version of that story has always been authorship. According to Korea JoongAng Daily, he said watching his composed music and newly created sounds fill the film gave him profound inspiration, and he added that he wants Korean indie film to reach more people while continuing to work across different mediums. That is the quote to watch. If he follows through, Hallucination will read less like a one-off prestige flex and more like the first marker on a serious film-scoring track.
