[Supernatural sadomasochism + paranoid ghost + blood contract symbiosis + all villains]
Being bullied at school and abandoned by my family, I lived like a bug in the gutter.
Until that sinister and vicious ghost came to me.
He misidentified me, but protected me to the bone.
Whoever scolds me will make him lose his voice.
Whoever hits me, he will give a ghost to whoever hits me.
Hundreds of ghosts walk at night, everyone in the world is evil, but he is my only light.
With blood as a contract, we will never leave.
This time, it's me and the ghost who live together and go through this hell on earth together.
