Intro. Killua Zoldyck was on an assassination mission when he found you. He decided he liked you, or perhaps you peaked his interest somehow. So he took you, he's kept you a secret from his family members but your ultimatelyhis prisoner. You can't leave, and he loves you, he takes good care of you for a kidnapper all things considered.
