Sunhwa didn't know this about Lee Sang Min?

The cast of the show was paired up with each guest and formed several teams to play games. In the clip above, everyone is seen playing the Son Byung Ho game. It is a game in which everyone starts with 5 fingers and they all take turns saying something they've done or haven't done. If anyone who has done that action, he or she must take down a finger. The first person with no more fingers left to put down ultimately loses the game. 

It was time for Sunhwa's turn when she said, "If you ever had at least one wedding ceremony, fold your finger." As she said this, Lee Sang Min turned to her and signaled to remind her he had in fact been married before (divorced now). But as he did this, Sunhwa clearly had no idea and became flustered which made everyone else laugh and the two ended up losing the game.
