SEE ALSO: Gong Hyo Jin reflects on the challenging filming of big-budget drama 'When the Stars Gossip'

On the July 23rd broadcast of 'One Night of TV Entertainment', the reporter asked the costars about the steamy poster for the drama, "When you film [a poster] like this, how do the actors feel?" Gong Hyo Jin shared, "We shot that after filming a lot of kiss scenes," and Jo In Sung finished her sentence, "We were able to film it comfortably."

When asked, "Don't kiss scenes feel different depending on the co-star? So how was it?" Gong Hyo Jin revealed an unexpected "inconvenience" when it came to kissing a handsome co-star with sharp features by sharing, "Whenever we film kiss scenes, his nose is so high it kept poking my eye." Jo In Sung wittily responded, "That day, I lowered my nose a bit, but it still [poked her]."
