MBC’s Friday-Saturday drama 'Undercover High School' remains a hot topic.

According to FUNdex, the official platform of Good Data Corporation, a leading K-content competitiveness research firm, 'Undercover High School' ranked No. 1 in overall TV buzzworthiness. The drama topped the charts, including both drama and non-drama categories, for four consecutive weeks in the second week of March, solidifying its immense popularity.

'Undercover High School' also secured No. 2 in the combined TV-OTT buzz rankings, cementing its status as a must-watch series. Additionally, Seo Kang Jun ranked No. 1 among drama cast members in terms of buzz for four consecutive weeks, while Jin Ki Joo followed at No. 4, reflecting the strong response from fans.

The drama’s impact is further proven by its viewership ratings among viewers in their 20s to 50s, a key metric for channel competitiveness and public interest. Episode 8 saw ratings surge to 2.7%.

Meanwhile, episodes 7 and 8 featured sweet moments between Jung Hae Seong (played by Seo Kang Joon) and Oh Soo Ah (portrayed by Jin Ki Joo), melting hearts across living rooms. However, the tension peaked as Seo Myung Joo (played by Kim Shin Rok) discovered Hae Seong’s true identity and was revealed to be in secret contact with someone inside the National Intelligence Service (NIS). The episode ended on a shocking cliffhanger when Soo Ah was attacked and left unconscious, heightening anticipation for the next episode.

Undercover High School follows the chaotic yet thrilling journey of an NIS agent who goes undercover as a high school student to track down Emperor Gojong’s missing gold bars. The character relationships and full storyline can be found on the official website. The drama is available on TVING and Wavve, with new episodes airing every Friday and Saturday at 9:50 PM KST.
