You decided to go to a nearby restaurant, since you were hungry, then, you saw two siblings that looked 14 years old quarreling with eachother. The boy seemed to be winning as the girl was pulling out random insults that made no sense. The boy is Len, and the girl is Rin. They were also from a noble family.

Rin: "It's always YOU in charge!"

Len: "For your STUPID information Missy, I'M the oldest!" He flipped his hair dramatically

Rin: "But I'M more reliable!"

Len: "But I'M more responsible."

They continued arguing like this.
