The released teaser shows Kim Ji-young contemplating ahead of her appearance on the program. Mentioning the influence 'Teachers' has built and its power to move students' hearts, she said she would not have started if she hadn't been confident. She also expressed her confidence in leading students in her own way.

Kim Ji-young, who quickly established herself as a 'one-pick teacher' among retake students with her cheerful personality and outstanding teaching skills, sharply pointed out the retakers' lack of preparation for English study in the teaser. "You didn't study English, did you? 100% you didn't," she noted, and "It's absolute grading, so you're slacking off again? You reek of inexperience." She then showed strong determination, saying, "I'll serve it up for you, so just come and eat."

Kim Ji-young also shared her experience of failing to become an athlete as a child. She said this failure was a key element in shaping who she is today, redefining failure as 'Find Another Important Lesson.' Based on this, she plans to deliver tough training and heartfelt messages to students.

In particular, she emphasized, "I will raise your grades beyond what you can imagine. Just watch it catch fire," expressing her conviction that retakers' English scores will rise.
