When Lee Seung Gi attended a press conference for his first film "Today's Love," the subject naturally turned to love. The film tells the story of a couple whose complicated relationship continues for 18 years. Their relationship is as changeable as the weather and as difficult to predict.

One of the characters, played by Moon Chae Won, is a witty weather forecaster. Her character Kim Hyun Woo, has been friends with elementary school teacher Kang Joon Soo for 18 years. Kang Joon Soo, played by Lee Seung Gi, often falls in love but he commits too much of himself to the relationship and as a result gets dumped by women on a regular basis.

Lee Seung Gi was pleased with his first film experience and spoke about the romantic comedy at a recent press conference for the film.

"I always dreamed about acting in a movie but now that it's become a reality I feel happy and honored," he said.

In real life Lee Seung Gi is dating Girls Generation singer and actress Yoona. So questions at the press conference turned to his real-life romantic relationship.

"I knew this question would come out," he said. "I came out here for my movie but no matter what comment I give, I think the articles will be too focused on that. So, I will give no comment."

Both Lee Seung Gi and Yoona have chosen to keep silent about their relationship, which made the news int he last months of 2013.

Emcee Park Kyung Lim tried to trick Lee Seung Gi into giving away some information about his relationship but Lee Seung Gi was too clever. Park asked if Yoona ever gave the actor any advice about acting and if she was aware of his movie.

"I won't comment on that either," said Lee Seung Gi. "She knows that I filmed the movie."

The actor obviously had a crush on Yoona long before they began to date and mentioned her when he was the host of "Strong Heart" as his ideal type. The couple reportedly began dating in September 2013. They were spotted on a date a few weeks later.

In November 2013 Yoona's agency, SM Entertainment, confirmed they were a couple. So did his agency, "Hook Entertainment." Both actors appeared in dramas in 2014. She starred in "The Prime Minister and I" with Lee Bum Soo. He appeared in 'You're All Surrounded" with Cha Seung Won and Go Ara.

"Today's Love" premieres on Jan. 15.
