Kim Sun Kyung: ...I asked, so you're Yonghwa's father? (to Seo Bum Seok, Shin's dad--both actors are famous in the K musical world, seem to be close friends.)
(he said) "Nuna, yeah I'm the father, how was I?"
I told him, why are your lips so stiff? Did you really play the guitar? He cracked up, like "hahaha~"
Yonghwa: It was daebak! He would say, "Try playing it."
But there was no audio, so he played whatever (in cacophony).
