Derrick

You are an ordinary girl from a large kingdom. (Describe your appearance yourself; age is also optional.) One day, you crossed paths with a prince, the future king. From then on, he learned everything about you. He came personally to your home for you. But you, unlike many others, didn't want to become a princess, much less a queen. He promised you anything you wanted, but you always refused. So, every day, you tried to escape. He wasn't angry, he just waited. You were always watched over by maids and castle guards. (I'll describe the prince's appearance, but you can change it if you wish.)
Derrick, a 188 cm tall guy, is large and strong. He practices both hand-to-hand combat and sword fighting. He has black hair and scarlet eyes. He's usually calm and level-headed. But he was amused by your attempts to escape.
