So after Younha introduced her sis and sang a duet with her, Jeong Junyeong entered the stage (he’s supposed to press the doorbell, but he kept pressing it for fun so it was like dingdongdingdongdingdong keke). Then Younha told him it was his sis birthday and brought in a cake. Haha he did light the match pretty well, fits his bad boy image. Then he was singing happy birthday to Younha’s sister at her request, when halfway he was like, what’s her name again? LOL Not paying attention when Younha introduced her! He told the audience vehemently, it’s our first encounter!
