I've been hunted for many times It's becoming a normal thing for me.   “It’s that boy! After him! Don’t lose him!”     Gun bullets had been common to me All the pain, all the wounds...it's like I'm immune.        “Shoot him!” “On the legs! Make him incapable of running!”     I've been kidnap for I don't know how many  Abandon places are not scary for me.       “We are at old barn near the XXXX hills. Bring the money or we’ll shoot him dead!” “Don’t bother with the police! Or else…”       Hospital has been my second home The color white became my favorite.       “What are his vitals…?” “Blood! We need more blood!”       My life was always in danger I'm forgetting the word 'safe'.       “Here, you’ll be much safer—or so I hope.” “Don’t worry, I increased the security here.”       Not until that person came Everything changed.       “Retreat! Retreat! We’re going to be annihilated!” “Dammit! Forget the money! Value your own life and run!”       I've been hurt but someone's protecting me. I'm almost forgetting about gun bullets.     “Sh*t! I missed! That F*cker blocks me!”       The word 'hurt' is starting to be replaced by 'safe'. I've been kidnap but have been saved too early.       “Stay here until I came back.
