tvN’s highly anticipated spy romance just dropped a teaser that’s got fans buzzing — and suspicious. Kim You Jung’s character delivers what looks like a heartfelt love confession to GOT7’s Park Jinyoung, but a single subtle gesture at the end suggests her feelings may be anything but genuine.

## What The Teaser Reveals

Directed by Yoo In Shik, known for *Extraordinary Attorney Woo* and the *Dr. Romantic* series, *100 Days of Deception* is a period spy romance set during the Japanese occupation of Korea. Kim You Jung plays Lee Ga Kyeong, a skilled pickpocket turned undercover independence spy who infiltrates the Japanese Government-General disguised under different identities. She grows entangled with interpreter Kim Tae Woong (Park Jinyoung), the adopted son of a top colonial official, as both characters navigate a web of mutual suspicion.

## Why the Ending Twist Matters

As the teaser unfolds, Kim Tae Woong grows increasingly wary of Lee Ga Kyeong’s shifting identities, while his adopted father urges him to win her trust and an independence fighter secretly orders her to do the same to him. The emotional high point comes when Lee Ga Kyeong tells him she has liked him since they first met — only for the camera to reveal her crossing her fingers behind her back, hinting the declaration may be a calculated lie rather than genuine affection. It’s a clever setup that promises a slow-burn romance layered with real historical stakes.
