Actress Jin Gi-joo is receiving a lot of love from viewers by showcasing her passionate side as a 'wannabe teacher.'

On the 28th of last month, Jin Gi-joo played the role of the dedicated temporary teacher Oh Su-a in the MBC Friday-Saturday drama 'Undercover High School,' doing her best to become a full-time teacher. Her performance, oscillating between comedy and seriousness, captivated the home audience.

On this day, after discovering that the main perpetrator of the school violence tormenting Lee Dong-min (Shin Jun-hang) was Park Tae-soo (Jang Seong-beom), Oh Su-a finally cleared up her misunderstanding of Jeong Hae-sung (Seo Kang-joon). Troubled by the truth of school violence and the crossroads of becoming a full-time teacher, Oh Su-a made an anonymous tip and, despite her intentions, she found herself wrongly accused while striving to protect Jeong Hae-sung, showing resourcefulness that kept viewers engaged throughout the broadcast.

Amid this, Jin Gi-joo's diverse performance as the charming teacher Oh Su-a, ranging from comedy to emotion, is capturing attention. In a scene where she unexpectedly runs into Jeong Hae-sung at a convenience store, reminiscing about a popular drama from the past, 'Romance,' she delightfully delivers the famous line, "You’re a student, and I’m a teacher," adding a touch of humor.

Additionally, when Oh Su-a, who received a thousand won from Dong-min's grandmother, gathered the courage to expose school violence and did her best for her student Jeong Hae-sung, who was on the verge of being expelled, her heartfelt and realistic acting fully immersed the audience, delivering both laughter and emotion.

Furthermore, as the past story of Oh Su-a becoming a teacher and her connection with Jeong Hae-sung is gradually revealed, it heightens curiosity. With her treasure-like charm, Jin Gi-joo, who has risen to be everyone's 'ideal homeroom teacher,' is anticipated to show her future endeavors through 'Undercover High School.'

Meanwhile, 'Undercover High School,' where viewers can meet Jin Gi-joo's new charms each episode, airs every Friday and Saturday at 9:50 p.m.
