Gong Hyo Jin, the star of "The Master's Sun," has been open about her relations with co-stars in the past and yet she has still not been able to avoid dating scandals.

When the actress appeared at the recent Teen Style Icon Awards, actor Ha Jung Woo, her co-star in the road movie "577 Project." When he called his co-star an actress "of fatal beauty," the emcee asked why she did not respond to his praise.

"It's risky for us to compliment each other because we keep getting into scandals," she said. "But thank you. I am now sick and tired of scandals with this guy. We know too much about each other to actually like each other.

The actor has more than once had to deny rumors that the two were seeing each other. In a recent interview he said that the rumors made no sense.

"Not with Hyo Jin," he said. "We're just fellow actors and consider each other family."

"It just cannot happen between him and me," said Gong Hyo Jin. "Ha Jung Woo likes women way too much. He's just not my style."

Gong Hyo Jin said she let the rumors about them slide because they were simply not true and she is always honest about her relationships. She was honest about the fact that she dated actor Ryu Seung Bum off and on for a decade. She began dating him on the set of "Wonderful Days" in 2001, although the two already knew each other from briefly attending the same school.

They starred together again in the 2002 comedy "Conduct Zero." They broke up in 2003, reunited in 2008 and appeared together in "Dachimawa Lee, directed by Ryu's older brother Ryu Seung Wan. In 2012 they ended their relationship but remained friends.

"Our relationship did not have a big problem, it wasn't as if there were many things worrying us," said Gong.

She said that even after the breakup they remain comfortable around each other.

"We seemed to naturally progress toward friendship," she said.

Gong has been candid about the fact that it's easy to become attracted to your co-stars but that the attraction often fades quickly once the drama ends.

When she was paired with So Ji Sub in "The Master's Sun," fans hoped the two would become a real-life couple. Although the actors were inseparable on set and were obviously fond of each other, no dating rumors between them have surfaced.
