Kim Seol, the beloved child actress who played Jinju in tvN’s hit drama Reply 1988, is set to appear on an upcoming episode of You Quiz on the Block and her appearance has already sparked excitement.

At the end of the December 10 broadcast, a preview showed Kim Seol joining the show as a guest. She originally gained nationwide popularity for her role as Jinju, the adorable younger sister of Sunwoo (played by Go Kyung-pyo) in Reply 1988.

Ten years ago, she charmed the entire nation with her chubby cheeks, bright expressions, and irresistible cuteness as Sunwoo’s younger sister Jinju. Now, she returns as a completely transformed teenager, drawing shock and excitement from fans who grew up watching her.

Recently, Kim Seol made headlines when her mother shared that she had completed coursework at a gifted education center. MC Yoo Jae-suk couldn’t hide his astonishment, exclaiming, “What happened? How did you grow this much?” His reaction mirrors that of countless viewers who were surprised to see how mature the once-tiny Jinju has become.

He went on to mention, “You became a hot topic after completing your gifted program. Your older brother attended it too, right?”

When asked whether her brother helped her with studies, Kim Seol made everyone laugh by responding: “ChatGPT is even better than my brother.”

The preview also shows Kim Seol performing spontaneous dance moves, proving that her natural charm, talent, and variety sense are still very much alive. With her growth in acting, academics, and performance, anticipation is building for her full segment on next week’s episode.

Alongside Kim Seol, the upcoming You Quiz episode will feature cartoonist-broadcaster Kim Poong, dentist Park Yoon-gyu, and actress Kim Da-mi, promising a diverse and dynamic lineup.

Born in 2011, Kim Seol made her debut in the 2014 film Ode to My Father before becoming a household name through Reply 1988 in 2015.

Her return to TV—more grown-up than ever—is sparking nostalgia and curiosity about her next chapter.
