## What Does the New Poster Show?

The poster shows the Government-General building at night, with five lit windows. Each window reveals a different character doing something suspicious:

| Window | Character | What They’re Doing |
| --- | --- | --- |
| 1 | Lee Ga Kyeong (as Geum Seo Hee) | Glancing around while pushing a cart with a five-layer cake |
| 2 | Sato Hideo | Pointing a gun at someone |
| 3 | Yoo So Ran | Reaching into her bag |
| 4 | Yoo Philip | Writing in a notebook |
| 5 | Sato Shinichi | Standing at the top with a champagne glass |

The tagline reads: “Plant a spy inside the Japanese-Government General of Korea.”

## Why This Poster Works?

- **Clever storytelling:** One image hints at several plots running at once.
- **Unanswered questions:** Why does Sato Hideo draw a weapon inside the building? How will Yoo So Ran and Yoo Philip’s separate plan connect to Ga Kyeong’s mission?
- **Rising tension:** Last episode, Ga Kyeong faced a crisis right after a secret phone call, when Sato Hideo turned up outside the door.

## Why You Should Watch?

If you enjoy period dramas with tense spy plots, undercover identities, and slow-burn romance, this one delivers all three. Kim You Jung and Park Jinyoung also give the story star power on both sides of the secret.
