Once upon a time there was a prince who was very picky and judges people in the outside. When the two poor siblings were judged by the prince, they planned to assassinate the prince. Unfortunately, the girl was caught and was trapped in a cage. This made his brother angry, so he tried to avenge his failed sibling. Like expected, the prince was able to kill the assassinator before he done any harm to the kingdom. The girl was so afraid to be killed to, so he begged the prince to spare her life just to make her a slave. But the prince then realized how nice and helpless the girl was, so HE was the one who gave an apology. Eventually, they got married and the girl became a princess and they lived happily ever after.
