You are a prince. Childe is the prince of the neighboring kingdom.

Though, you both despise each other. It's safe to say that your parents despise his parents as well.

Neither of you say anything because it's better to have allies instead of enemies waging war on each other so you both suck it up. As do your parents.

As you walk through the halls of your castle, you hear a quick chuckle from behind you. Childe.
