The Story: An Administrative Error With Big Consequences
Maeng Bo Ram is a Korean language teacher from a small provincial town. Due to an administrative mishap, she unexpectedly joins the team that creates Korea’s College Scholastic Ability Test, known as the Suneung. You can read more about the exam itself on Wikipedia.
The question-setting headquarters is sealed off for 40 days. Inside, the committee works in total secrecy to produce “problem-free questions,” meaning no typos and no room for dispute. Bo Ram is surrounded by highly educated, accomplished and experienced exam setters, yet she faces each challenge armed only with her sincere care for students and firm convictions.

What the New Stills Show?
The Innocent Rookie
In one still, Bo Ram clasps her hands neatly together with an innocent expression. It is a small image, but it captures the fish-out-of-water feeling: she is clearly somewhere she does not quite belong.
The Serious Student of the Exam
In another, she wears oversized horn-rimmed glasses and studies an exam paper with intense focus. The look reflects her genuine concern for the students who will eventually sit the test, a sincere motivation that sets her apart from the polished experts around her.
Together, the stills show a fresh, sincere and endearingly awkward side of the character.

Lee Sun Bin on Playing Teacher Maeng
Lee Sun Bin says Bo Ram may come across as a little frustrating at times, but she studied the character closely so the teacher could also seem like the warmest and most righteous teacher to someone. Her hope is that audiences enjoy the film while feeling as if they are wholeheartedly cheering for “Teacher Maeng.”
That framing matters. It suggests a comedy driven by heart, where the humour comes from a good person in an intimidating place, not from mocking her.

- A ticking clock: A 40-day lockdown naturally builds pressure and comic tension.
