Karina, Wonyoung, and Byeon Woo‑seok Collaborate on a Christmas Song
Karina of aespa, Jang Wonyoung of IVE, and actor Byeon Woo‑seok have been confirmed to appear together in a new Christmas song project. The announcement was made in early December, accompanied by a short teaser video that immediately drew attention online.
The combination of two leading female idols and a popular actor has sparked interest, particularly given the different backgrounds of the participants.
50‑Second Teaser Video
The teaser runs for approximately 50 seconds and is available on Dolphiners Films’ official YouTube channel. In this short clip, Byeon Woo‑seok appears dressed as a priest, while Karina and Wonyoung wear nun outfits. The visual presentation leans on religious motifs, with simple, controlled imagery that conveys a calm and somewhat mysterious atmosphere.
Despite the brevity of the teaser, the styling and composition of the scenes hint at careful planning behind the project.
Additionally, the video was produced in collaboration with Google, using the image-generation model Nano Banana Pro from Google Gemini 3 and the video-generation model Veo 3 in some scenes, adding extra depth and detail to the visuals.

Additional Cast and Visual Atmosphere
The teaser also features appearances from actors Park Hee‑soon and Moon So‑ri. Their inclusion adds subtle depth to the visual narrative, even though the video does not provide explicit storytelling. Scenes include interior shots of a chapel, quiet moments among the main cast, and a funeral procession led by Byeon Woo‑seok’s character.
Overall, the video maintains a restrained tone, emphasizing the presence of the performers rather than elaborate plot details.
Release Schedule Unconfirmed
At this time, details about the full song, video length, or official release schedule have not been made public. The teaser serves primarily to announce the collaboration and introduce the cast to the audience. Viewers are left with a sense of anticipation, as the project hints at more content to come without revealing concrete information.
Focus on Casting
One of the most talked-about aspects of this project is the casting itself. Bringing together two top female idols from different groups alongside a rising actor is an unusual combination for a Christmas-themed release. The lineup has become the central point of discussion on social media and in fan communities, with attention focused on how the three performers will interact visually and musically in the final version.
Can’t wait to see what comes next!
