A romantic connection is brewing between Seo Kang-jun and Jin Ki-joo.

The 4th episode of the MBC Friday-Saturday drama 'Undercover High School' (planned by Nam Gung-seong-woo, written by Lim Young-bin, directed by Choi Jeong-in, produced by Neo Entertainment and Slingshot Studio), airing today, features the comedic and melodramatic encounters between Jung Hae-sung (played by Seo Kang-jun) and Oh Soo-ah (played by Jin Ki-joo), igniting a teacher-student romance.

In the previous 3rd episode, the witty exchanges between Hae-sung and Soo-ah, who met at a convenience store, increased the laughter index of home viewers. While they were playfully bickering over a drink, Soo-ah lightheartedly remarked, "You're a student, and I'm a teacher," evoking memories of the past drama 'Romance.' As a result, the viewership rating for the 3rd episode recorded its highest at 6.7%, according to Nielsen Korea's metropolitan household standards, and the ending scene where Hae-sung dragged former president (played by Jo Jae-yun) to the school violence committee soared to 7.8%, heightening expectations for the 4th episode.

Ahead of today’s broadcast, stills have been released capturing sweet moments between Hae-sung and Soo-ah. The captivating tension before they share a kiss, as well as Hae-sung grabbing Soo-ah's shoulder and her startled reaction, are intriguing.

In the 4th episode, the story of Hae-sung and Soo-ah throwing off their dislike and growing closer is depicted. Particularly, as Soo-ah visits Hae-sung's home, unexpected events unfold. As seen in the stills, situations arise where they share a kiss due to an unexpected accident (?), while Soo-ah also doubts Hae-sung's suspicious behavior, leading to a comical series of events.

As the broadcast featuring the two's heart-throbbing moments approaches, attention is drawn to the reasons behind the changes in Hae-sung and Soo-ah's relationship. There is rising anticipation for the 4th episode, as it portrays whether Hae-sung's identity as a National Intelligence Service agent gets exposed and whether he begins to genuinely offer his heart to Soo-ah, defying expectations.

The 4th episode of 'Undercover High School' will air today at 9:50 p.m.
