tvN’s upcoming drama “The Smile Has Left Your Eyes” has released new teaser videos.

The new mystery melodrama is about a murder suspect (Seo In Guk), a woman who falls in love with him (Jung So Min), and an older brother (Park Sung Woong) who’ll do anything to protect his sister.

The first teaser clip shows Seo In Guk and Jung So Min’s characters first meeting through a friend (Seo Eun Soo) and slowly developing a strange relationship with one another. Seo In Guk shows interest in Jung So Min and she seems flustered at first.

In one of the scenes, Park Sung Woong witnesses Jung So Min getting dropped off by Seo In Guk and angrily says “Why are you getting out of his car? Why?” Through the short clip, romance, heartbreak, pain, and anger are all expressed.

Another teaser includes a title that is a fun play off of Jung So Min’s last leading role as Yoon Ji Ho in the drama “Because This Is My First Life.” The teaser is a compilation of the actors’ previous dramas, with dramatic music and comedic lines. Jung So Min and Seo In Guk show off their great acting skills as they shed tears, take on funny scenes, and add sweet romance to the clip.

“The Smile Has Left Your Eyes” premieres on October 3 at 9:30 p.m. KST, and will be available on Viki!
