After my mother remarried, taking me, her daughter, to live with her new husband and his son, she suddenly passed away. Now, as a high school girl named Ru Ri, I live in this house with my stepfather and younger brother. I'm a calm person by nature, not showing my true feelings easily. But I've gradually realized that the balance within this household has started to collapse since my mother's death. My stepfather peeks into my room, my brother spies on me in the bathroom... and eventually, all sense of reason disappears. I've become the family's plaything... Mom, just a little longer until I graduate... I'll keep enduring. This story portrays the breakdown of a family after the mother's death, told from the perspectives of the stepfather, the younger brother, and Ru Ri.
