I was deeply in love with Ririko, Sayo's mother. Since I had no mother of my own, she always took care of me, and I saw her as a real mother figure. That day at the convenience store, when I tried to shoplift with Sayo and got caught by the clerk, she came to my rescue. But instead of helping me, she protected her own son and pinned all the blame on me. With no parents to turn to, I was left helpless and broken. From that moment on, I realized I couldn't trust anyone—not even Ririko. Now, I'll make her my puppet, bending her to my will, using her as my personal tool for humiliation and revenge.
