A long time ago, in a city rules by a barbaric king, there was a princess. In the kingdom, when someone goes to trial, they are presented two doors, one with a tiger, and one with a lady. Depending on which door the accused chooses, it determines if he is guilty or not. If it is the tiger, he will be killed. If it is the lady, the man will marry her as a reward.
The princess had fallen in love and everything was going fine. However, the king found out about the affair and he made the man go to trial. The princess managed to find out which door had which person/animal and the man was depending on her to tell him.
The princess also knew the woman behind the safe door. She knew that she liked the man and would happily marry him if he chose the right door.
The princess needs to think if she loves the man enough to save him or if she will get so jealous that she should lead him to his doom. She probably thinks that if the man opens the door with the woman, she will not be able to handle it and will be sad forever. However, if she leads the man to the door with the tiger, she will never see him again and she will feel guilty.
In the end, she points to the door on the right. The author tells us to think about what she would have chosen: for her lover to die or to be married with another woman. I think that she would choose the door with the tiger. The author already tells us that she and her father are semi-barbaric. She will MOST LIKELY be selfish in this case rather than to be jealous and miserable. We do not know what she chose to lead the man to but this is what I think that she is thinking.
