Lee Seung Gi may be dating YoonA from Girls’ Generation but he is completely shot down by Moon Chae Won in the newest trailer for their upcoming film “Today’s Love.”

The film, which is also known as “Love Forecast,” focuses on Kang Joon Soo (Lee Seung Gi), an elementary school teacher who dedicates too much of himself in relationships. He has a long-term friendship with Kim Hyun Woo (Moon Chae Won). Hyun Woo is a sarcastic weather forecaster.

The film provides the analogy that love can be like the weather, with all of its fluctuations.

Actor Lee Seo Jin (Wonderful Days) portrays Dong Jin, Hyun Woo’s senior at work.

T-ARA’s Hwayoung portrays Hee Jin and After School’s Lizzy is Min Ah. The idol-heavy cast also includes rocker Jung Joon Young as Andrew.

“Today’s Love” marks the film debut for Lee Seung Gi, who most recently starred in the SBS drama “You’re All Surrounded.” The film is also a reunion for Lee Seung Gi and Moon Chae Won, who starred opposite one another in the 2009 drama “Brilliant Legacy.”

“Today’s Love” opens in theaters in Korea on January 15.
