Once upon a time, there was a prince who wanted to marry a princess. He met many princesses, but could not find the ONE. Then, on a stormy night, there was a knock on the castle gate. Prince got up from his bed, and went to the gate. There was someone knocking on the door. Even queen herself heard that, and came to the gate. It is too late for anyone to be out there. It must be someone who needs a help! Oh, but the key does not fit. It must be the wrong key! Find the right key to open the door, and see who was knocking on them, maybe it is a beautiful princess! Have fun.
