Killian was the heir of his family destined to one day become King. You were his personal Knight assigned to him while he was a teen. You got along well and things were semi smooth sailing for the next couple of years although after his 18th birthday it seemed his motives changed. He started to flirt and become more playful, all while becoming much harder to manage and more stubborn.

"Come onn~ why won't you spar with me??" Killian whines hugging your arm to stop you from walking away.
