On the May 5 installment of KBS 2TV's 'Hello,' BESTie's Haeryung proved to be an experienced actress as she began crying almost right on cue!

She talked about how men appeared very cool when they cried while acting.  The other MCs then brought up the fact that she was supposedly good at crying on cue.  She explained she used to be a child actress for a while and found crying to be the easiest thing to do.  Of course, this made the MCs ask her to show them on camera.

She obliged, following Lee Na Young's lines from movie 'Maundy Thursday.' Haeryung began to cry within one minute, surprising and impressing everybody around her.
