Imagine being locked away for 40 days to write the toughest exam in the country, and you only got the job by mistake. That’s the premise of ***Ugly Duckling Ms. Maeng***, a new Korean comedy film. Its latest character posters borrow the look of a famous exam-prep book cover, and they’re packed with jokes.

## The Premise

**Maeng Bo Ram** (Lee Sun Bin) is a Korean language teacher from a small provincial town. Due to an administrative error, she lands on the team that creates Korea’s [College Scholastic Ability Test](https://en.wikipedia.org/wiki/College_Scholastic_Ability_Test), also called the CSAT or Suneung. The question-setting headquarters is sealed for 40 days while the committee works in total secrecy to produce questions free of typos and disputes. Chaos, naturally, follows.

## Ugly Duckling Ms. Maeng: Meet the Characters

| Actor | Character | Role | Poster Vibe (paraphrased) |
| --- | --- | --- | --- |
| **Lee Sun Bin** | Maeng Bo Ram | Gen Z Korean language teacher | Confident pose; insists the exam must be fair no matter what |
| **Yoo Jae Myung** | Moon Joo Yeol | Head of the Korean language question-setting committee | Sharp glare over his glasses; calls his scheming “strategic thinking” |
| **Kim Young Min** | Park Kyung Tae | Self-proclaimed righteous head of the review committee, the “walking red pen” | Steely look; sees far too many problems with the questions |
| **Jeon Seok Ho** | Ki Jun Soo | Operations committee employee | Bright, office-politics smile; urges working well, not just hard |

## Why the Posters Work?

The design parodies a popular CSAT study-book cover, a sight every Korean student knows well. Each witty tagline hints at a personality and at the mishaps waiting inside the sealed headquarters.

- **Bo Ram** is the passionate newcomer with principles.
- **Joo Yeol** brings power-player energy with a bumbling side.
- **Kyung Tae** is the perfectionist nobody can satisfy.
- **Jun Soo** adds a dose of workplace realism.

## Why Watch It?

- **A fresh setting.** The secretive world of exam-making is rarely seen on screen.
- **A strong comic cast.** Veteran scene-stealers pair with Lee Sun Bin’s lead.
- **Universal relatability.** Anyone who has sat an exam will recognize the pressure and the absurdity.

While you wait, catch Lee Sun Bin in *Boyhood* and Yoo Jae Myung in *Love Me* on Viki.
