Suh Kang-jun shared a surprise kiss with Jin Gi-joo.

In the 4th episode of the MBC Friday-Saturday drama "Undercover High School" (planned by Nam Gung-seong-woo, written by Im Young-bin, directed by Choi Jeong-in, produced by Neo Entertainment and Slingshot Studio), which aired on the 1st, Jung Hae-sung (played by Suh Kang-jun) was depicted tracking the truth behind the second rumor spreading within the school.

The viewership rating that day recorded 8.3% based on nationwide households and 8.3% based on households in the capital region, setting a new record for its highest viewership rating. In particular, the scene where Sua stepped on a massage ball in the rooftop room and fell into Hae-sung's arms raised the rating to 10.3%. Furthermore, the 2049 viewership rating, a key indicator of channel competitiveness and public interest, increased significantly, recording 2.4%.

In the 4th episode, a school violence committee meeting was officially held regarding the incidents involving Hae-sung, Lee Dong-min (played by Shin Jun-hang), and Park Tae-soo (played by Jang Sung-beom). Hae-sung instructed to find Gu Sang-tae (played by Jo Jae-yoon), the owner of a gambling site, to testify in order to prove that Tae-soo was gambling, and thus appeared late at the school violence committee meeting with Gu. This revealed that Tae-soo had used an illegal gambling site, and Dong-min also exposed Tae-soo's previous misconduct, bringing the situation to a close.

The second rumor surrounding Byeongmun High School has also been revealed. A female student who had always ranked second out of jealousy pushed her friend, who had been first, off the rooftop, and soon after the female student who killed her friend was also discovered as a corpse. As a result, a rumor spread that one should not be at school when the clock strikes, sending chills down the spines of those who heard it.

To uncover the truth behind it, Hae-sung examined the pendulum clock located on the first floor of the school, and during this process, he discovered that the same type of clock was in the student council room. Thus, Hae-sung decided to become a student council member in order to enter the student council room. He collaborated with four domestic teams to fulfill one of the conditions to become a member, which was to submit a list of 100 recommenders. They lured students by offering free sandwiches if they signed, and Park Mi-jeong (played by Yoon Ga-i) and Koh Young-hoon (played by Jo Bok-rae) even danced enthusiastically. Hae-sung, feeling embarrassed, pretended not to know but was dragged onto the stage by Head of Team Ahn Seok-ho (played by Jeon Bae-soo) to join in a dance party, causing laughter.

Meanwhile, an unexpected situation arose where Hae-sung had to leave school for reserve forces training. Hae-sung used the excuse of not feeling well and managed to escape, but the situation escalated when Oh Sua (played by Jin Gi-joo) decided to visit his residence. Hae-sung's residence, the rooftop room, was in a state of emptiness, and there was a chaotic rush by the four domestic teams to make it look habitable. Just as Ahn, Mi-jeong, and Young-hoon were finishing decorating the house and about to leave, Sua arrived, prompting the three to hurriedly hide inside the closet.

At the end of the broadcast, the kiss moment between the four domestic teams brought laughter. Sua stepped on a massage ball on the floor and fell, causing Hae-sung, who was facing her, to fall as well and share a kiss. Furthermore, Mi-jeong, who was hiding in the closet, accidentally kissed Young-hoon, who was about to sneeze, causing him to faint and fall outside, creating an unprecedented situation. Sua humorously asked Hae-sung, "Can someone explain this situation?"

Meanwhile, MBC's "Undercover High School" airs every Friday and Saturday at 9:50 p.m.
