Basically what happened here is that PD-nim is saying what they’re going to do for the next scene (Two Step Kiss). He said that they’re going to kiss.. then cuddle too – basically act sweet to each other. He said it in a teasing manner of course. And Shinhye felt shy that’s why she laughed and buried her face to PD-nim. HAHA
They just love teasing her. She’s so cuuute too. (⁀ᗢ⁀)
