K-drama fans, get ready for a school story like no other! Undercover High School is gearing up for its highly anticipated premiere, and actress Jin Ki Joo is bringing a whole lot of heart to her role as the passionate and dedicated teacher, Oh Soo Ah!

This upcoming drama follows Jung Hae Seong (Seo Kang Joon), a National Intelligence Service agent who goes undercover as a high school student (yes, you read that right! 😆) to uncover the whereabouts of Emperor Gojong’s missing gold bars. But while he’s busy playing detective, Oh Soo Ah, played by Jin Ki Joo, is just trying to navigate her own struggles as a devoted, easygoing, and endlessly caring teacher who dreams of securing a full-time position. 🏫💛

Jin Ki Joo revealed why she was drawn to Undercover High School, sharing that it felt like a fun and lighthearted drama that viewers could enjoy effortlessly. “It’s like a ‘mealtime companion’—something that’s easy to digest but still meaningful,” she explained.

When it came to bringing Oh Soo Ah to life, Jin Ki Joo went all-in! She even sought out real teachers to better understand the challenges they face in balancing personal goals with their devotion to students. Talk about dedication! 🙌📖

Of course, she couldn’t forget to mention her co-star Seo Kang Joon, who she described as a veteran actor and a "dependable leader" on set. With their incredible synergy, it’s no wonder filming was such a blast! 🥰🎬

Describing her character with three key words— chaotic, students, and a teacher who's like a friend—Jin Ki Joo emphasized that her students are everything to her. They are both her biggest motivation and the heart of her journey. 💕📚

As for why fans should tune in? Jin Ki Joo sweetly encouraged viewers to wrap up their weekend nights with some fun and heartwarming moments in Undercover High School.
