The pink meeting between Seo Kang-joon and Jin Ki-joo is making the small screen excited.

MBC’s Friday-Saturday drama “Undercover High School” (played by Lim Young-bin, directed by Choi Jeong-in) has dominated the viewers’ first row of home, crossing genres from romance, mystery and comic. In particular, the chemistry between Jung Hae-sung (Seo Kang-joon) and Oh Soo-ah (Jin Ki-joo) of “Chapsaje” is receiving enthusiastic responses from viewers. In addition, the relationship between the two is changing over and over again, making the play more interesting.

First, Haesung and Sua’s first meeting was an anaerobic view itself. Sua had an inevitable encounter in coincidence when Haesung, a customer, saved her when she was threatened by a bully at her mother’s store. Also, Sua fell in love at first sight when she saw Haesung’s handsome face, but when he appeared as a student in her class, she turned on the light in her eyes and watched closely. Hae-sung, who was taken by Su-ah for drinking, embarrassed her by responding by talking informally to her and calling her “that side.” In addition, even when the two met at a convenience store, they bickered over a drink, creating an anaerobic chemistry and giving a pleasant laugh to the small screen.

Their meeting, which had been tangled from the beginning, became even more twisted. Sua suspected that the gunman in the school’s old building resembled Hae-sung, and that he immediately overpowered the group of president Koo (Cho Jae-yoon), who was brought in during the school violence committee. In response, Sua conducted a joint operation (?) with fellow teacher Kim Rian (Lee Min-ji) to examine the agents of the NIS’s fourth team, who are people around Haesung.

While Hae-sung and Su-ah’s “Chap-sa-je chemistry” aroused viewers’ interest, the two quickly became close as Hae-sung’s identity was revealed. Sua questioned Haesung on the day security guard Kim (played by Koo Min-hyuk) died, saying that he was at the scene, and Haesung was eventually found out. After that, the two began to cooperate, not cooperate, and Sua turned red when Haesung held her hand and said, “I’ll protect you.” In particular, in the sixth episode, Haesung found out that Sua was a childhood friend, Bong-ja, and the scene where Haesung pulls Sua to avoid the water baptism of a motorcycle passing by in the sudden rain colored the small screen with excitement. This amplified questions about what direction the relationship between Haesung and Sua will change in the future and how their romance will unfold.

Undercover High School, which has such a variety of stories that properly target viewers’ tastes, is becoming more popular day by day. The first broadcast began with a highest viewership of 6.4%, and the ending scene of Haesung and Sua’s romance rose to a maximum viewership of 10%. The rapid development of Haesung from the first episode to the moment when he became a high school student and started an undercover investigation, to the moment when Haesung’s identity is revealed, is contributing to the rise in viewership.

In addition, 2049 viewership, a key indicator of channel competitiveness and popularity, rose vertically from 2.0% in the first episode to 3.3% in the sixth episode, ranking first among all programs aired on Saturday as well as at the same time. This is the only three-point level among all channels, and the buzz was proved by capturing the younger age group by topping the drama-non-drama for two consecutive weeks and topping the list with actor Seo Kang-joon.

Undercover High School airs every Friday and Saturday at 9:50 p.m.
