Tea arrived and Zero took time to talk to the princess, easing her into the more difficult topics after gaining her trust and admiration. The doctor soon found out that Princess Dorothy was actually a smart girl who just wasn't exposed to the world thanks to her overprotective family. The lady was a good age of twenty and was considered rather young for a dwarf. However, she inherited her mother's intelligence and would have been a very capable ruler if not for the fact that her father caged her in the palace like a bird.
Fae King Vivian was the only person Princess Dorothy had the pleasure of meeting who paid attention to her as an individual and not a princess of Rocket Mountain. Although Zero didn't understand romantic love, he could understand why the princess had fallen for the Fae King.
