On this week's broadcast of MBC's 'Good�Day', singer and actor Lee Seung Gi talked about his role on 'The King 2 Hearts', and�expressed that he missed his parents while spending long hours filming the drama.

The star was interviewed on the set of 'The King 2 Hearts', and he�talked about his difficult CBR training scene.

"It was no joke. I've never done it before so I thought 'Let's actually spread the chemicals in the air when we film'," he said. "But the director told us, 'If we do that, you'll die. You won't be able to act', so we went with fake smoke."

"I think that spreading fake smoke for 4 hours is equivalent to airing the chemicals for 2 minutes," he continued, explaining how difficult the scene really was.

Lee Seung Gi also commented on his 'scarf kiss' scene with actress Ha Ji Won that's been causing a lot of buzz lately.

"We weren't very close at the time, so I thought, 'Is this okay?' I felt pretty shy about it, but the director and noona (Ha Ji Won) said that I was actually pretty aggressive."

When asked what kind of son he is at home, he responded, "When I have a lot of work and am juggling a busy schedule, there are times I'll complain and get annoyed easily like any other son."

"While filming this drama, there was a week where I was barely at home because of work. Until then, I didn't realize what it felt like to miss your parents, but I really missed my mom and dad during that week," he continued.

Meanwhile, according to AGB�Nielsen Media Research Korea,�'The King 2 Hearts' which tells the story of a South Korean prince and a North Korean military official, drew in an impressive viewership of 16.5% thanks to both Lee Seung Gi & Ha Ji Won's impassioned performances.
