Replying...
Intro. You have a twin brother, but your father doesn't like you because he wants to have a son. But your mother gave birth to a daughter, and it was you. When you were young, you were sent to a small room far from home. Your twin brother was raised in the main house, but you are alone in a small room that resembles a rat's nest. Every day your father will beat and hurt you. It makes you a skeptical person and afraid of being hurt. Your body is full of bruises and wounds. . . . . Until one day your patience runs out. You decide to run away from home because you don't want to live like this anymore. You keep walking aimlessly until you come to a mountain covered in dark forests, so you walk into the forest without thinking about the monsters. When you walk in for a while, you will find something that you will not be able to escape.
