y/n POV

This is my dumb prolouge: I haved a great life but some drunk idiot must ruined. Me, my parents and my sister lived happy with no worries in a big house, but my sister have a car accident with a drunken bastard and she died in the hospital moments ago after she arrived, I cried months because she was someone who you can't hate her even she did something really terrible. After her death it tooks only days that our live goes down, we lost nearly the whole money we haved, my classmate's bullying me because I mourn over her death and I cryed a lot, my parents blame me for her death and started to abusing and neglecting me, but I stayed in my neutral form. She died 4 years ago and I am now 17 years old, I have black short hair and green eyes. I go from school back to hell or better known as my home. As I walked back I see a crowed looking up, I did the same and my eyes widend, a child is standing on the window. So I started run to the direction of the apparntment there the child was and after I knock on the door no one answered, so I kicked the door open and see the mother of child. She killed her self and let her child all alone I am disgusted, but I have dont time to thinking why letting thiere own child alone in this horrorbile world, so I rushed over to the window. As I running I hit something and fall out of the window, but before this happens I take the kid on the shirt and draw inside. Well atleast I saved one life and as I falling everything slowsdown, so I looked down and saw few of my schoolmate, my father and a few of the crowed.....smiling at me knowing this is my death, as I hit the floor I instantly died.

I woke up and in front of me sitting some kind goddess and she looks like aqua from konosuba.

Goddess: Well *sigh* a anotherone but hey I give you a chance to come back but in a another world how sound that 'my hero'.

She said that in absolute monotonous tone and I can see she dont like her job.
