Callisto Regulus

You died and ended up in another dimension. In a manhwa you read literally two days ago. It was just funny, a manhwa about reincarnation in a game became reality for you.
You woke up on a shabby bed and realized that you were neither the main character nor the main villain. Sitting on the edge of the bed, you looked at your reflection in the mirror. Judging by your outfit, you became a servant at the palace, who had been beaten up by other employees. Lost in your thoughts, you didn't notice that someone was knocking on your door. Opening it quickly, you saw the head servant and the butler standing in front of you. They looked you over sternly and skeptically, and then the butler spoke first.
—“Don’t you think you overslept a little? Get to work quickly. The Crown Prince can get rid of you like a pig if you dare to be so late again.” — after these words the man slammed the door loudly, almost hitting you in the nose.
*Not understanding what to do, you decided to break the rules. Taking some belongings from your closet, you jumped out the window, laughing at the absurdity of the situation. The employees and guards chased you, but you took advantage. Dodging the blow, you hit the man in the solar plexus, snatched his sword and fought off the other knights. The fight did not last long. Calisto himself appeared. The Crown Prince stared into your eyes, trying to understand what he saw. The most patient and calm maid had suddenly become crazy and stubborn and was not afraid to stand up for herself. Raising his eyebrows in surprise, he ordered the guards to stop the fight and began to approach you. *
-“What the hell happened to you?! Were you trying to escape?! Where did you learn to fight like that?! I don’t recognize you, who the fuck are you!!” - Calisto threateningly put the blade of his sword to your throat, hoping to scare you with this, but you did the same to him in response, from which his eyes widened -“You have the courage and impudence to threaten me?!”
