Sunny appeared on KBS 2TV's 'Happy Together 3' on August 11!

First, Sunny said, "When I call Jo Se Ho, he doesn't pick up the first time often.  It's fun teasing him.  I call him until he picks up.  I can be clingy."  Cao Lu, where you at!

He replied, "After recording, he told me to go visit Girls' Generation's waiting room, and I tell her I'm going to make Girls' Generation wait for me.  There are times Sunny secretly pays for the bill at restaurants. When I tell her, 'I earn money, too, so why are you paying?' she replies, 'Oppa, I'm Girls' Generation,'" making everyone crack up. He continued, "That's why I call her CEO."

Their friendship is cute!
