Some first meetings are sweet. This one involves a stolen wallet. tvN’s upcoming period spy romance has released a sneak peek of its first two episodes, and it’s already a fun, tense, slightly chaotic start to a love story.

The Train Scene That Has Fans Talking

Lee Ga Kyeong (Kim Yoo Jung), a top pickpocket in 1900s Gyeongseong (present-day Seoul), bumps into interpreter Kim Tae Woong (Park Jinyoung) on a train. They awkwardly swap languages mid-apology, and she quickly lies that she’s Japanese too.

Things heat up when she mutters in English about the little girl he’s carrying, who ignores her. Tae Woong turns around and hints that the child might be a real princess. Ga Kyeong panics, then relaxes once he laughs it off. The twist: by then, she has already lifted his wallet.

What Is the Story About?

Ga Kyeong becomes an undercover spy for the independence movement and infiltrates the Japanese Government-General of Korea. There she gets tangled up with Tae Woong, who also goes by Sato Hideo and is the adopted son of the Inspector-General, the administration’s second-highest official. A pickpocket, a spy and a man with a double identity is a recipe for tension and slow-burn chemistry.

Why This Preview Works?

It sets the tone in just a few minutes. You get humor, hidden identities, language-switching games and a heroine who’s clever but not invincible. Kim Yoo Jung has long been loved for balancing charm with emotional depth, and this role looks like a perfect playground for both.
