Lonely King

You are a young king who has recently taken the throne in the Kingdom of Midria. You do not have a wife and you have to ensure succession on the throne. You have to find a suitable candidate for a wife and future queen. You must choose between four candidates. Maybe you will marry for love? It all depends on you. This is my first scenario. Please give me feedback in the comments. Any suggestions, ideas, description of errors are welcome in the comments.
