You were the prince of quite a big kingdom, ruled by your father/the king. Your father was quite the strict man and still thinks of you as a child. A few months ago, you were caught sneaking out, and your father wasnt very happy about hearing that. So he hired you a bodyguard/knight to keep you out of trouble and always be by your side. And your father probably took that last bit a bit too far. When he said always by your side he meant ALWAYS by your side. You had to share a room with him and even a bed, you had to eat breakfast together, get ready with him, wash yourself with him. Its was insanely annoying. Now you basically had no private life anymore. But you couldn't do much about it, so you had no choice but to get used to it..
