Nobody saw this coming, and yet here we are — absolutely losing our minds over Kang Dong Won, Park Ji Hyun, and Um Tae Goo transforming into a retro co-ed K-pop trio for their upcoming comedy film Wildsing. The newly dropped teaser for their fictional group TRIANGLE’s comeback single “Love is” is already the most chaotic and delightful thing on the internet today.

What Is Wildsing About?
Wildsing tells the wonderfully chaotic story of TRIANGLE — a once-wildly-popular co-ed trio that crashed into obscurity after an unfortunate incident. Years later, the three members attempt to reunite and mount a full comeback, navigating the messy, hilarious, and emotionally messy road back to the stage.
Think behind-the-scenes idol drama, nostalgia for the golden age of K-pop, and a generous helping of comedy gold — all wrapped in the aesthetic of late 1990s Korean pop culture.
Meet the Members of TRIANGLE
Kang Dong Won plays Hyunwoo, the group’s leader and self-proclaimed dance machine — legendary for his signature headspin moves. The red bandana and highlighted hair in the teaser poster are pure 90s idol energy, and frankly, it’s working on every level.
Park Ji Hyun steps into the role of Domi, the group’s only female member and its visual centre. Her standout presence in the teaser immediately makes her the heart of the group — exactly as a centre should be.
Um Tae Goo rounds out the trio as Sanggu, the youngest member and high-energy rapper, undergoing one of the most striking visual transformations of his career. Meanwhile, Oh Jung Se plays Sung Gon, a ballad singer forever stuck in second place behind TRIANGLE — a role that already sounds hilariously tragic and perfect.
They Actually Trained Like Real Idols
What makes this even more impressive — and endearing — is the level of dedication behind the scenes. Film insiders revealed that the cast underwent intensive training in both choreography and rap comparable to what actual K-pop idols go through. The teaser’s sharp dance breaks set to old-school hip-hop beats are the proof, and they are genuinely impressive.
Going well beyond standard film promotion, the production is treating TRIANGLE as a real artist rollout — releasing the title track “Love is” as an actual pre-release single on May 21 ahead of the film’s June 3 theatrical debut.
