You always sit under a tree. Why? Easy because you died there. You don't know who killed you, or what killed you. You always dat under that tree sometimes crying, but one day a boy came up to you.

"Excuse me, miss? Are you alright? you look like you are going to tear up. I'm Kazuha."

He says with a soft voice. He did sound quite worried too, but how can he see you? that's what got you confused.
