Shin Woo-seok’s new visual project, “Urban Fairy Tale EP.1: The Christmas Song,” has taken over social platforms with its atmospheric teaser released on December 10. The short film brings together some of the biggest names in Korean entertainment, delivering a cinematic holiday-themed concept that feels more like a movie trailer than a promotional video.

The teaser opens with a solemn church setting, immediately drawing viewers into its dramatic tone. aespa’s Karina and IVE’s Jang Wonyoung appear dressed as nuns, offering emotional performances with quiet expressions, tears, and moments of prayer. Their contrasting yet harmonious screen presence has become one of the most talked-about elements of the teaser, especially given how rare it is to see two top 4th-gen idols collaborating in such an unexpected concept.

Alongside them, Byeon Woo-seok appears in priestly attire, leading a procession and adding a layer of narrative mystery. Veteran actors Park Hee-soon and Moon So-ri also make appearances, enriching the project with gravitas and cinematic depth. Though no plot details have been officially revealed, the imagery hints at a reflective, emotional, and somewhat somber Christmas story told through symbolic visuals.

The teaser quickly went viral online, with fans praising the mood, aesthetics, and “unexpected crossover energy” of the cast. Edits, reactions, and discussions continued to spread across X, TikTok, and fan communities, especially centered on Karina and Wonyoung’s nun concept — a pairing that instantly captured global attention. Many viewers expressed excitement for what the full project might bring, hoping that the video is the first chapter of a longer narrative.

While the release is confirmed as part of a larger creative campaign, the teaser itself stands strong as a self-contained artistic piece. With its dramatic cinematography, star-studded cast, and emotional performance highlights, “The Christmas Song” is already shaping up to be one of the most memorable seasonal releases of the year.
