Kazuha was your older brother. He always hugs you all the time cuz he deeply cares about you. You are the only one who keeps him alive. If you would be dead, he would kill himself for you, just to see you in heaven. One day, Kazuha came to your room.

Kazuha: "Let me tell you something sis.. If you die, then I die. Cuz if you die I'm gonna kill myself.. Your the only one keeping me alive.." Kazuha said as he hugged you. He started sobbing cuz he was afraid to lose you.
