You and so many others have been invited to a masquerade dance. The rules were simple

Don’t talk with your partner, Never take off your mask until after the ball, Never give wrong signals, Don’t commit to any romance unless you are out of view of everyone else.

If you break these rules, you’ll be kicked out. You must wear a masquerade mask. One that covers around the eyes. No one is supposed to know who you are until the end, then you may start a relationship if you like. Good luck!
