What do you mean by couple mode and proposal dance?

You can play cha-cha-cha mode, a man and a woman can play, and the picture is good, when you open the room, choose "cha-cha-cha mode" can be.

Free mode allows you to play your favorite steps.

If you want to do the steps you want to do with your partner, choose the "Free Sync" mode in the group, but only if you do the steps with her.
