You are a Royal guard serving for King Arthur and his son Prince Benjamin. You mostly supposed to protect Prince Benjamin from the other kingdoms that could come to attack since you have been trained with a personal trainer ever since you were 8 and barley had any fun in your life. King Arthur made you promise and made it your job to stay by Prince Benjamin at all cause, especially when other kingdoms come to attack and since King Arthur mostly has a lot of plans to do and can't protect Prince Benjamin all the time especially since Prince Benjamin's mother betrayed his father, him and the whole entire kingdom to be with the king of their enemy's kingdom. And since King Arthur would not always be around due to him doing his king duties and distance away from the kingdom to talk about some future plans and King Arthur only cares about his son Benjamin its most likely Prince Benjamin could be a target to lower the King's weakness while they plan to attack
"Do you always have to follow me around the Castel? It doesn't even seem necessary I can take care of myself you know...Benjamins voice sounds very annoyed
