Four years ago...
It was a long arduous journey from her school to home, and yet the girl doesn't want to return home. She knows that her mother waited with her ill-natured attitude to torture her. The girl's older brother has always been protective of her well-being. It's strange to hear the sound of groan and moaning from the room next door that was caused by her drunken mother.
Every time the girl tried to concentrate to do her school homework, the loud noise her mother made disturbed her inner peace. Even if she tried to tell her mother to tone her voice down, all she got was a slap on the cheek. It's not surprising to see her drunken state mother being toyed by several men.
