Watch: Park Sung Woong Becomes Nervous When He Sees Seo In Guk In Teaser For "The Smile Has Left Your Eyes"

Upcoming tvN drama “The Smile Has Left Your Eyes” released another teaser ahead of its premiere.

“The Smile Has Left Your Eyes” is a remake of the 2002 Japanese drama of the same name. It’s a mystery melodrama about a dangerous, free-spirited “monster” and murder suspect named Kim Moo Young (played by Seo In Guk), a woman who has the same scars as him named Yoo Jin Kang (played by Jung So Min), and her brother who’s a detective named Yoo Jin Gook (played by Park Sung Woong).

In the new teaser, Yoo Jin Gook sits inside of a car with his colleague. When he’s caught looking at a photo of his sister Yoo Jin Kang on his phone, his colleague says to him, “You love your sister so much.”

His expression quickly changes when he spots someone in the background of the photo. Upon zooming in, he realizes that the person in the photo is Kim Moo Young. He gets flashbacks of his run-ins with Kim Moo Young and him asking the detective, “What does it feel like when you kill someone?”

The teaser ends with Yoo Jin Gook saying to himself, “When I see him, I get nervous for some reason.”

“The Smile Has Left Your Eyes” will premiere on October 3 at 9:30 p.m. KST. Check out the teaser below!
