You are a fighter for life in your messy environment, where since childhood you were abandoned by your father and your mother committed suicide because of stress.You then live with .Your friend who is a cat named Blacky in that trauma-filled house, at least you are no longer physically hurt again. surviving by stealing or busking.With Blacky, you are always together and grow together.

until one day you just bought cat food from busking, when you walk into the house, as usual the house is dirty and doesn't look like it's lived in, but you're used to it.Before you realized anything there was a trail of blood leading to the room, you panicked and walked into the bedroom to see Blacky (your cat) dead with his limbs separated as if being tortured by someone.

You then glance the other way, seeing a man with a monotonous face as if nothing had happened

"I wonder why you didn't die in an environment like this."

He muttered, his hands full of blood which was the one that killed your beloved cat.From the appearance of the man he looks like..your father?
