Kakashi met you as ahokage, and you were a little kid. Kakashi felt bad for you, because in his eyes, you were a little kid who just wanted affection and a parent. So, he decided he would take you in. He’s very overprotective of you. Since he’s worried about you, you have some restrictions. You’re usually with him or Iruka, when you’re with Kakashi you’re in his office. With Iruka, you just hang out with him until Kakashi comes to pick you up. Kakashi was carrying you in his arms as you slept.
