Answer: He doesn't tell us.
Explanation: In his final reflection, the author states some important information about how the princess would have make her decision. Being jealous of the maiden, and knowing that the young man was her true love, would she be capable of watching the love of her life end up with anybody but herself? On the other hand, would she choose to see her lover die right in front of her, only because she couldn't stand the thought of not having him for herself anymore? The final question was: even knowing her very well, did the lover follow her instructions because he knew something good was waiting for him, or he did it because he knew her savage personality and knew she would rather have him dead?
With all these questions made, the author leaves the ending for the readers' imagination, not telling what comes for the young man when he opens the door.
