Seo Kang-joon played the role of Jung Hae-sung, the ace agent of the National Intelligence Service, in MBC Undercover High School, which aired on the 22nd. On this day, Jung Hae-sung faced a series of crises, with four domestic teams of the NIS being disbanded under false accusations and receiving instructions to leave the school from Seo Myung-joo (played by Kim Shin-rok), chairman of Byeongmun High School.
Jeong Hae-sung soon used the crisis as an opportunity to counterattack. "I want to correct what's wrong."Under a sense of responsibility, Jeong Hae-sung focused on Emperor Gojong's mission to recover the gold bars. He performed a thorough analysis as well as a clear brain play using his intuition.
After struggling, I found a secret space, but there was no gold bullion there. Instead, Jung Hae-sung faced his father's body, which turned white. Jung Hae-sung made viewers cry with a mixture of complex emotions such as sadness and anger.
"Genre changes, too. Like Jung Hae-sung's line, "Depending on what choice the protagonist makes," Seo Kang-jun presented 'Seo Kang-jun Gift' across various genres such as comic, mystery, and melodrama in the play.
Seo Kang-jun once again proved the wide spectrum of acting by portraying Jung Hae-sung as a delightful comic, the process of finding the secret of a ghost story is a tense mystery, and the deepening relationship with Oh Soo-ah (Jin Ki-joo) as a melodrama full of excitement.
Meanwhile, MBC Undercover High School, starring Seo Kang-joon, airs every Friday and Saturday at 9:50 p.m.
