Actors Lee Seo Jin and Kim Kwang Kyu stepped up to support singer Hwasa during her performance.
On October 31, videos of the “NepFesta” concert performance held on the same day were uploaded to social media and online communities.
In the clip, Lee Seo Jin made a surprise appearance during Hwasa’s performance of “Good Goodbye,” holding her pair of white high heels in one hand as he shared the stage with her.
After the song concluded, Kim Kwang Kyu also joined them on stage. Hwasa handed over the microphone, saying, “With the end of the year just around the corner, could you elders offer a few words of wisdom for the audience here before making your exit?”

Taking the microphone, Kim Kwang Kyu shouted loudly, “Just do whatever you want!” Lee Seo Jin then took the microphone and offered a clean, warm message with his signature nonchalant yet charming dimpled smile: “Have a wonderful weekend today.”
When Hwasa announced an encore to the audience, saying, “I’ll do just one more song before I go,” Lee Seo Jin gently took her arm and playfully tried to lead her offstage, causing another outburst of laughter across the venue. The audience responded enthusiastically, chanting “Lee Seo Jin!” as he exited.
This surprise appearance was reportedly filmed as part of SBS’s My Genie Secretary, heightening anticipation among viewers for the chemistry between Hwasa and her “one-day secretaries,” Lee Seo Jin and Kim Kwang Kyu.
