Newcomer Seo Su-min, who made a powerful first impression as So Ji-sub’s daughter in SBS’s Friday–Saturday drama Agent Kim Reactivated, is going viral after fans discovered she already runs a YouTube channel with 100,000 subscribers.

In the June 26 premiere of Agent Kim Reactivated, Seo plays Kim Min-ji, the only daughter of Manager Kim (played by So Ji-sub) — a gutsy high schooler who forges ahead despite her mother’s absence — instantly grabbing viewers’ attention.

Her performance was remarkably assured for a debut. In particular, the heartbreaking scene where she witnesses her father kneeling on her behalf and then breaks down moved viewers to tears and earned rave reviews.

Born in 2007, Seo Su-min is signed with Y1 Entertainment, home to Shin Sung-rok and Lee Beom-soo. She launched her personal YouTube channel last year and has already surpassed 100,000 subscribers. One ultra-short clip, just 44 seconds long, has now crossed 3 million views.

Comments under the video read, “That nostalgic ‘ulzzang’ vibe,” “She must look even prettier in real life,” “Her visuals are unreal,” and “We’re rooting for her acting career,” among many others.

With her fresh visuals and performance that exceeded expectations, Seo Su-min made a memorable mark from episode one — and all eyes are on the rising star to see how far her potential will take her.
