Actress Go Hyun-Jung has been gaining attention and affection for a short yet heartwarming exchange online with child actor Kim Dong-ha, who played her on-screen son in JTBC's 2021 drama, "Reflection of You."

On June 2, Go reposted a nostalgic Instagram story initially shared by Kim, which featured a coffee truck believed to have been gifted to the actress.

The child actor captioned the image, "Back when I was Hee-joo's son more than anyone else's," referring to his role as the son of Go's character in the drama.

Go replied to the post with a short but deeply affectionate message: "Dong-ha ya!!"

The phrase, a heartfelt Korean call of someone's name, immediately resonated with fans, many of whom remarked on the emotional weight carried in just two syllables.

"She called out his name with so much warmth," one fan commented online. Another added,

"You can feel the motherly love through just that one word."

The exchange has elicited emotional responses on social media, with many praising Go for having maintained a close relationship with her co-stars.

Some fans noted that even years after the show ended, the maternal energy she brought to her role clearly remains.

The moment was also a reminder of Go's enduring visibility following personal difficulties, including her widely publicized divorce from Chung Yong-jin, vice chairman of Shinsegae Group.

Even through her struggles, Go is still perceived by fans as a matronly figure, whether off-screen or on.

The reunion post serves as a poignant reminder of the emotional connections that can form from Korean TV dramas, some of which endure long after the cameras stop rolling.

Go has not issued any further statement regarding the exchange.
