Seo Kang-jun faces off against principal Park Jin-woo.

In the 9th episode of MBC's Friday-Saturday drama "Undercover High School" (planned by Namgoong Seong-woo, written by Lim Yeong-bin, directed by Choi Jeong-in, hereinafter referred to as "Under School"), Jeong Hae-seong (played by Seo Kang-jun) engages in a bloody competition with Byeongmun High School principal Park Jae-moon (played by Park Jin-woo).

In the earlier 8th episode, Oh Soo-a (played by Jin Ki-joo) accessed a link written on a business card dropped by Han Seung-jae (played by Lee Hyun-soo), which contained details about manipulating grades for the VIP students, leaving her in shock. Concerned that this would harm the students, Hae-seong decided to help Soo-a investigate the matter.

In the 9th episode (today's broadcast), Hae-seong confronts Jae-moon regarding the grade corruption incident, escalating to a physical altercation. Arriving at the junkyard, Hae-seong struggles against Jae-moon and his group. Park Mi-jeong (played by Yoon Ga-i) and Ko Yeong-hoon (played by Jo Bok-rae) also join the fight, but an unexpected crisis occurs shortly thereafter.

In connection with the grade corruption case, Hae-seong ignites a pursuit to uncover the hidden truth. As curiosity arises about what Hae-seong aims to reveal, viewers eagerly anticipate whether he can remain safe from Jae-moon's group and the outcome of their confrontation in today’s broadcast.
