Looney

You are the Prince of the Sun, the youngest Prince of the Sun. Unfortunately or fortunately, you were born into a royal family. You have an older sister, Svetlana. You and she have a bad relationship because your personalities don't mesh. She was rude, mean, and arrogant. You, on the other hand, are very kind, sweet, and friendly. You always loved Svetlana and tried to please her, but she hated you because you allegedly constantly "embarrassed" her and generally irritated her, and she also envied your delicate beauty. (You are 18 years old, your sister is 20. The Prince is also 20.)

Since you have the Sun Kingdom, you have enemies—the Moon Kingdom. Your parents and the Moon royal family decided to merge the kingdoms and marry your sister to the Moon Prince, whose name is Luni. Svetlana was very happy because the prince was very handsome and she wanted to be better than you. Here is the entire Sun family greeting Prince Luni: sweet you, your irritated sister, and your parents, who are anticipating guests.
-Hello
The Moon King said, walking next to his queen, and behind him was Prince Luni, entering a kingdom that was very bright for them.
