STAYC Sieun Reunites With Her Childhood Co-Star After 13 Years

Some reunions are worth the wait. Thirteen years after they last shared a screen together, STAYC's Sieun and actress Jung Ji-so sat down face to face once again — and the result was pure nostalgia.

The reunion took place on STAYC's YouTube series titled Hanjanhasshin, where Jung Ji-so appeared as a guest in an episode uploaded on March 11. The two had not seen each other since their appearance together on the children's variety show Makiraesho back in 2013, when both were aspiring young performers navigating the entertainment industry.

From Child Stars to Industry Icons

At the time of their original meeting, Sieun was a child actress with credits in several Korean dramas, while Jung Ji-so was building her own acting career. Their paths diverged dramatically after the show — Sieun eventually transitioned from acting to become a member of the K-pop girl group STAYC under High Up Entertainment, debuting in November 2020. Jung Ji-so, meanwhile, rose to international fame through her role as the daughter of the wealthy Park family in Bong Joon-ho's Oscar-winning masterpiece Parasite in 2019.

During the episode, Sieun recalled how Ji-so had been a quirky and generous older figure during their shared time on set, often teaching her new things and keeping the atmosphere light. The warmth between the two was immediately apparent as they reminisced about their childhood days in the industry.

A Full-Circle Moment

The reunion resonated with fans who appreciated seeing a different side of Sieun beyond her idol persona. For longtime STAYC supporters familiar with Sieun's acting background, the episode served as a touching reminder of the journey that brought her to where she is today.

Jung Ji-so, whose filmography now includes critically acclaimed projects alongside some of Korea's biggest names, showed genuine warmth reconnecting with her childhood colleague. Their conversation offered viewers a rare glimpse into the personal bonds that form behind the scenes of Korea's entertainment world.

STAYC's Growing Content Universe

The Hanjanhasshin series has become a popular segment on STAYC's official YouTube channel, featuring the members in relaxed, conversational settings with various guests. The show gives fans a more personal look at the members outside of their music promotions, and the Jung Ji-so episode has quickly become one of its most talked-about installments. With STAYC continuing to expand their content output alongside their music career, moments like these help solidify the personal connection between the group and their dedicated fanbase.
