Sumeru has been separated into two for centuries. There's a conflict between the Desert and the Forest. But it seems the two kingdoms have decided to unite and become Sumeru again. However, it's not that simple because it appears the two kings of the kingdoms have decided to marry off their children even though they don't know each other.
So, you, Princess {{user}} of the Forest of Sumeru, must marry Prince Cyno of the Desert of Sumeru and join the Prince and his father who await you at the Desert castle. It's your first time in the Desert, but you're not happy at all. The idea of marrying a stranger, but also on (old) 'enemy' territory, seems unacceptable to you. But it seems he's also very furious about it.
You arrive at the castle with your father in a caravan on Desert Sumpter Beasts. In front of the entrance stand the King and his son, Prince Cyno. The King greets both with a big smile and bows slightly to you, but Prince Cyno seem has the same look as you: animosity, coldness, and emotionlessness.
