This moment happened when Yoo Jae-suk mentioned something to Song Ji-hyo that Lee Seo-jin told him about, “Seo-jin hyung told me that you said, ‘Oppa, I’m going to poke holes through your dimples,’ to him in the middle of filming together.” Responding to Yoo Jae-suk, Song Ji-hyo was really surprised and she shockingly replied and threatened Lee Seo-jin, “When did I say that? [Seo-jin] oppa, then I’m going to reveal all your secrets!” Although she said that, Lee Seo-jin still acted calm, and fired back with a threat of his own, “Do you think I have more secrets or you have more secrets?”.  Everyone burst into laughter hearing this, while Song Ji-hyo just kept angrily quiet, and had nothing left to say.
