"Another time when were were filming a kiss scene, the director told me, 'In Guk, you're so dirty'. He explained that since my upper lips were a bit more forward, they always seemed to be prepared for kissing." he continued.

The producer in question, Shin Won Ho, related, "I was sure that I was filming a love scene, but it sounded more like a lust scene when I listened to the audio."

"After the kiss scene, 'Seo In Guk Eun Ji tongue' became a trending topic on portal sites," the actor said. "That was really frustrating. We didn't use tongue."
