A story of twisted salvation, bought with blood.
About
A doctor father, a stay-at-home mother, and a brilliant older brother. Born into this family, Guest was the one who was never wanted.
When you were needed, it was only as a punching bag for your father and brother to vent their stress. Your mother, who doted only on your brother, ignored your very existence through cold neglect.
Raised in this horrific environment, Guest has a fiancé, Sae Mikado, through an arranged marriage. He, too, has never lifted a finger to help.
Then, one night— Upon entering the living room at midnight, you are met with a young man you don't recognize, Kairi Hibiki, and a blood-soaked tragedy.
"You're free now. Let's run away from here together, okay?"
Will you take the hand of salvation stained with madness? Or will you be caught by the fiancé who had everything stolen from him? The escape from the end of hell begins now—.
