Actor Seo Jun-young Wraps Acclaimed Theater Debut in 'Happiness' After Two-Month Run

Award-winning K-drama actor Seo Jun-young has officially completed his first theatrical performance, wrapping up a critically acclaimed two-month run in the stage play "Happiness" at Seoul Naru Art Center. The production, which ran from January 1 through March 1, 2026, marked a significant milestone in the versatile actor's career as he successfully transitioned from the small screen to the live stage.

The play "Happiness" tells a deeply moving story about a husband living with Alzheimer's disease and a wife affected by Cornelia de Lange syndrome. The emotionally demanding material required its performers to navigate complex themes of love, memory, and devotion, making it a particularly challenging debut for any actor new to theater.

A Triple-Cast Production

Seo Jun-young shared the demanding lead role in a triple-cast arrangement alongside veteran actors Hong Kyung-in and Lee Tae-il. The triple-casting format, common in Korean theater, allowed each actor to bring their unique interpretation to the role while ensuring the production could sustain its intensive performance schedule over the two-month run.

The arrangement also gave audiences the opportunity to experience different emotional textures within the same story, with each actor bringing their own depth and nuance to the portrayal of a husband grappling with the devastating effects of Alzheimer's while maintaining his bond with his wife.

Heartfelt Reflections on the Experience

Through his agency T and I Cultures, Seo Jun-young expressed deep gratitude for the experience. The actor reflected on the unique challenges and rewards of performing live, noting that the immediate connection with the audience provided a fundamentally different kind of artistic fulfillment compared to his extensive television work.

The transition from screen to stage is one that many Korean actors find both daunting and rewarding. The live nature of theater demands a different kind of discipline and vulnerability, as there are no second takes or editing to fall back on. For Seo Jun-young, embracing this challenge speaks to his commitment to growth as a performer.

A Distinguished Television Career

Seo Jun-young has built an impressive body of work in Korean television over the years. He is known for his memorable performances in several critically acclaimed dramas, including the historical epic "Deep Rooted Tree" and its spiritual successor "Six Flying Dragons," both of which showcased his ability to bring historical characters to life with conviction and emotional depth.

His romantic comedy credentials were firmly established with "Another Oh Hae-young," where he demonstrated a lighter, more playful side of his acting range. More recently, he earned widespread recognition for his work in "Golden Mask" and "Brave Yong Soo Jung," both of which highlighted his ability to handle complex dramatic material with sensitivity and skill. His role in "Queen of the House" further cemented his status as one of Korean drama's most reliable and talented performers.

Award-Winning Recognition

Seo Jun-young's talent has been formally recognized with multiple prestigious awards. He took home an honor at the 2023 KBS Drama Awards for his compelling performance in "Golden Mask," a drama that demanded both emotional vulnerability and dramatic intensity. The following year, he was again celebrated at the 2024 MBC Drama Awards for his work in "Brave Yong Soo Jung," confirming his consistent ability to deliver award-worthy performances across different networks and genres.

These accolades reflect not just momentary brilliance but a sustained commitment to excellence that has defined Seo Jun-young's career trajectory over the years.

Support from Colleagues

The actor's theater debut also attracted attention from his industry peers. Fellow actress Ahn Yi-seo attended one of the performances, showing the kind of collegial support that characterizes the close-knit Korean entertainment community. Her presence in the audience was noted as a warm gesture of encouragement for Seo Jun-young's bold new artistic venture.

Looking to the Future
