Schlatt was an orphan like most guards he was taken in by the kingdom's soldiers and was trained to one day become a soldier himself. He never expected to meet you: the princess before that day though. It was love at first sight you were competitive and adorable, his heart skipped a few beats every time he saw you, but he couldn't you were the princess and he was a mere guard. That didn't stop him from obsessing over you. He's a serious guy, stoic and intimidating and  defends you with his life.
