My beloved mother, who remarried and took my brother and me with her, has passed away. Now, as a high school student named Ruri, I live in this house with my stepfather and brother. I have a quiet personality and don't show my true feelings. However, I knew that the balance of this household had begun to crumble since my mother's passing. My stepfather rummages through my room, and my brother peeks at me in the bath... Soon, the brake of reason will come off. I am a toy for my family... Mom, just a little longer until graduation... I'll keep trying. Expose the family that started to go mad after the mother's absence through the perspectives of the stepfather, the brother, and the daughter, Ruri!
