It's been a while since dating rumors between lead stars of "Moonlight Drawn By Clouds' Park Bo Gum and Kim Yoo Jung surfaced. While no one seemed to confirm their true relationship, the lead actor was reportedly giving hints to their fans.

The KBS2's TV series started airing on August 22 and continued until last month, featuring 18 episodes. And just after the show began, rumors surrounding Park Bo Gum and Kim Yoo Jung's real life love affair spread like wildfire. However, when asked, the lead actors only responded by telling that they were just doing their job well. But it now looks like they are actually dating according to some media outlets.

In a report by Soompi, on November 13, Kim Yoo Jung appeared on KBS2's "2 Days and 1 Night," wherein Park Bo Gum reportedly is being super sweet to his co-star.

While they were taking a short break, cast member Kim Jong Min suddenly mentioned that Park Bo Gum was also a recent guest on the show because seeing Kim Yoo Jung reminded him of her "Moonlight Drawn by Clouds" co-star.

Cha Tae Hyun then gave an impromptu call to see what Park Bo Gum was doing and mentioned that there was a special guest today and angled the camera towards Kim Yoo Jung, Park Bo Gum indirectly commented on her beauty and said, "Is today's guest a doll?"

The two former co-stars sweetly waved to each other, as Park Bo Gum continued, "So pretty."

The actor also confirmed if she is the only guest, before he sweetly said that he has to watch it for sure then. Park Bo Gum also asked everyone to take care of Kim Yoo Jung while filming, and showed a large amount of affection for his "Moonlight Drawn by Clouds" co-star.

The on-screen couple reportedly dated one time as told by Kim Yoo Jung.

"Park Bo Gum oppa is really good to me. We're like siblings. Before we started production, we wanted to get close to each other so we did script readings together and went out to eat, but it felt awkward," she said.

"When filming started, becoming closer happened naturally as we went through the difficulties together. Now not only Bo Gum oppa, but Jinyoung oppa and Kwak Dong Yeon oppa and all the seniors feel like family."

For now, neither Park Bo Gum and Kim Yoo Jung have confirmed if there is an ongoing romantic relationship between them.
