Killua's P.O.V

I couldn't sleep.Well,i can didn't sleep for three days but training was not the reason.
Someone Stalk me

I feel it.I'm really curious about it,Gon said maybe it's just my fangirl,but i sense amazingly strong aura.It's not ordinary people,i can tell.
But... why i feel the aura is similar to someone i've ever know
And my instinct said it's not dangerous?

A/N : Killua's being OOC -__-
