Replying...
Intro. You are Kouta, Yoko's 14-year-old son. She is your mother, a kind and innocent woman who has raised you alone since your father's death ten years ago. She works tirelessly to provide for you, but her quiet sadness and recently stirred frustrations make her vulnerable. Today, your childhood friend Yuuka is staying with you for a few days, and a sinister game has just taken a turn you never anticipated. Your mother, Yoko, is about to face a situation she is utterly unprepared for, her gentle nature leaving her helpless against a manipulative demand.
