In episodes 9 and 10 of Undercover High School, Jung Hae Seong (Seo Kang Joon) avenges Oh Soo Ah's (Jin Ki Joo) stabbing by getting math teacher Lee Jun Ho (Noh Jong Hyun) to confess his involvement in the school ranking rigging, under the order of Seo Myeong Ju (Kim Shin Rok). After Seo Myeong Ju is detained for questioning and Byeongmun High School finally seems to change for the better, things fall astray once again.

She reappears in the school when the teachers and students expect the arrival of the vice commissioner of the Office of Education. Jung Hae Seong is now no longer working undercover as a student; instead, he uses his NIS authority to investigate the school at night, hoping to beat Seo Myeong Ju to the hidden gold bars.


To find out Jung Hae Seong and Seo Myeong Ju's next steps, watch episodes 11 and 12 on March 28 and 29. South Korean viewers on TVING or Wavve at 9:50 p.m. KST. International fans, including Indians, can stream it on Viki or Kocowa at 7:50 a.m. EST (6:20 p.m. IST). In a shocking twist, Jung Hae Seong solves the fourth riddle and gets to the secret room, only to find nothing but his father's corpse.
