When does a couple spending time together officially become dating? Not yet, say actors Jung Ga Eun and Bae Ho Geun of their developing friendship.

Although the media has called them a couple, for now they say they are not officially dating, only spending time together as friends.

The couple met on set but it was not the set of a drama or film they were acting in together. Jung Ga Eun and actress Hwang In Young are good friends, so Jung was often on the set of her Hwang's new film "Hero" to support her friend.

Bae Ho Geun is also in that film so the two met on that set. They started spending time together.

But as any kdrama fan knows, two actors can find it hard to spend time together without anyone noticing.

It was just a matter of time before the actors' agencies were called on to comment about their relationship. The official response was vague. They are interested in each other, his agency's representative said, but it is hard to call them an official couple yet.

Her agency said that she met him on the set of "The Hero" but that they are not in a relationship.

Sources close to the actress say the two have met up and really like each other but it's hard to say that they are officially dating. They are just friends at this point.

His friends agreed, saying the two, who are both 35, have become close, frequently spending time with other friends and acquaintances but it's too early to call them a couple.

You can hardly blame them for not defining their relationship as the minute they do, they will be scrutinized even more closely. And that can put a lot of pressure on a new relationship.

The actress plays An Jin Joo on "The Master's Sun." She played Jang Hye Bin in "A Thousand Kisses" and had cameos in "High Kick 2" and "Family." She has appeared on several variety shows, including "Rollercoaster," "Sponge 2.0," "Heroes," and "Sunday Sunday Night."

Bae Ho Geun has appeared in the films "You're My Pet, " "Heartbeat," and "A Hot Goodbye." He debuted in the film "Bravo My Life" and his new film "Hero" will premiere on October 8. "Hero" is a film about a boy who becomes a vampire after an unexpected accident, and then becomes a national hero.

It should be interesting to see if they show up at the premiere together.
