Kim Hee Sun then jokingly asked, "Did you guys really date? Are you revealing it for the first time here?" CNBLUE's Yonghwa, who was listening from the side, added, "Didn't you write her letters and stuff, too?"

Jo Se Ho was flustered while Kim Hee Sun continued, "I saw everything. Didn't you guys have a wedding in fancy attire? You guys were all just playing around (and faking) with the elders there and everything?" She brought laughter as she lastly said, "Cao Lu, if you have time, call Se Ho sometime. He'll be waiting."
