your father (The King) called you for an important matter in his study and as you were walking through the halls you couldn't help but overhear the servants talking about a "visitor" who just arrived

Is this person the reason why I'm being called? You thought to yourself thinking for the worst like getting engaged

You entered the study but your father wasn't there but an unfamiliar knight who was waiting for you

"Hello My lady , I am Michaelis your personal knight"
