Killua P.O.V

I sigh,my body only feel pain.Everyday my life fill with torture.
I heard a crying sound,a girl?
I saw a little girl sat behind the tree.Weird,i didn't feel her appearance.
"Ne,why are you crying?"i cover my mouth when i realize my voice still hoarse from screaming and insulting my mother.
It scare her,she cry even louder.
I smile and pat her shoulder,i know she has the same age as me.
"Tell me,what happen?" I ask her sweetly.
Wait
"My parents torture me harshly..."
What am i think i'm doing?!
"I felt pain,it's scary!"
I can kill this girl in instant
She smile,make all my hesitation melt.
I'm not gonna kill her
I grin "It's okay.I'm an assassin too"
From now,i swear i will protect her
"My name is (Y/N)
No matter what
