Baby Jinjoo’s Grown-Up Appearance Leaves “Reply 1988” Cast In Tears At Reunion
As one of the most beloved K-Dramas of the 2010s, Reply 1988 has remained popular even years after its release.
Starring a lineup of popular actors, the series tells the story of five students from Ssangmun-dong, who grew up as friends.

The drama also featured many secondary characters that viewers grew to love, including Jinjoo, the younger sister of Sung Sun Woo. The adorable toddler’s nonchalant reactions to things going on around her and her love of snacks were popular among netizens and even became reaction memes.


2025 marked the tenth anniversary of the program, and the cast reunited and filmed a special variety-style program. The three episodes are currently scheduled to air on December 19, but previews were recently released, teasing what the cast will be up to.

Baby Jinjoo’s actress, Kim Seol, was not listed or shown in the initial promotional content, so it came as a surprise when she appeared in a teaser.
The teaser shows the cast having strong reactions to someone arriving, with Ko Kyung Pyo and Kim Sun Young, who played Jinjoo’s brother and mother in the series, tearing up.
Though she is not fully shown, the peek given of the person arriving matches Kim Seol’s current appearance as seen in her upcoming Yoo Quiz on the Block appearance.


Netizens reacted strongly to the video clip, reflecting on how much time has passed and how much she has grown!
