Twist-Filled Romance: K-Drama Tops Buzz Rankings for 4 Weeks!

On March 17, FUNdex, the official platform of Good Data Corporation—a leading institution specializing in K-content competitiveness—reported that MBC’s Friday-Saturday drama Undercover High School has ranked No. 1 in overall TV buzz (including both drama and non-drama categories) for four consecutive weeks.

This impressive streak highlights the show’s growing popularity. Additionally, it secured the No. 2 spot in the TV-OTT integrated buzz rankings, solidifying its reputation as a “must-watch live” drama.

The drama’s leading actor, Seo Kang-joon, who plays the undercover agent-turned-high school student Jung Hae-sung, has also been a major topic of discussion. He has topped the TV drama actor buzz rankings for four consecutive weeks, proving his lasting appeal. Jin Ki-joo, who portrays Oh Soo-ah, followed closely, securing the No. 4 position, further demonstrating the strong fan engagement surrounding the drama.

The show’s dominance is further reflected in its 2049 viewership ratings, a key metric for measuring a channel’s competitiveness and audience engagement. Episode 8 saw the rating soar to 2.7%, capturing viewers' attention and solidifying its position as one of the hottest dramas currently airing.

Meanwhile, the latest episodes (Episodes 7 and 8) showcased a heart-fluttering romance between Jung Hae-sung (Seo Kang-joon) and Oh Soo-ah (Jin Ki-joo), adding to the drama’s emotional depth. However, tensions escalated as Seo Myung-joo (Kim Shin-rok) discovered Hae-sung’s true identity and was revealed to be secretly communicating with someone inside the National Intelligence Service. The episode ended on a dramatic cliffhanger, with Soo-ah being ambushed by an unknown assailant and collapsing, heightening anticipation for the next installment.

Undercover High School follows the story of a National Intelligence Service agent who goes undercover as a high school student to track down the missing gold treasure of Emperor Gojong. With its mix of espionage, action, and high school drama, the series has captivated audiences. The character relationships and full synopsis can be found on the official website. The drama airs every Friday and Saturday at 9:50 PM KST.

Meanwhile, Seo Kang-joon is set to make a special appearance in Netflix's upcoming drama Boyfriend on Demand (working title).

Boyfriend on Demand is a romantic comedy that follows Mirae, a webtoon producer exhausted by the realities of daily life, who subscribes to a virtual dating simulation to experience love with an AI-generated boyfriend. With its relatable workplace setting and a fresh take on romance through a subscription-based virtual dating world, the drama is expected to revolutionize the concept of modern love.

The series has already confirmed singer-actor Seo In-guk and actress Jisoo as its lead cast. Now, with Seo Kang-joon—often dubbed the “ultimate TV boyfriend”—joining the lineup, the drama promises to bring an even richer and more diverse romantic experience to the screen.
