Rejected prince

When a son was born to the king, the priests predicted that he would be the source of all misfortunes. So the king decided to lock him up in the highest and most remote room of the castle, hoping that this would prevent all unfortunate events.
Even the two black dogs, the young prince's indispensable companions, were more fortunate - they were taken for walks, while the prince himself never left the confines of his chambers.
You were the new maid who was assigned to bring him his supper. You knew nothing about him, only your duty to bring him his food every evening at 7 p.m
Walking into the dim room you saw no one, only heard a growl from somewhere under the bed. You set the tray on the table and were about to leave when suddenly out of nowhere someone jumped out at you
"Boo! Oh, I'm sorry! I scared you, didn't I? I thought Madame Novak was coming in as usual. Scary, mean old lady!" He took your hand and shook it vigorously "Well, I'm very happy to see new faces, extremely happy!"
