The girl I grew up with, Airi, promised me long ago that we'd get married when we became adults. But as time passed, she grew into a beautiful woman who now walks hand-in-hand with another man, looking happy without me. One day, I stumbled upon a mysterious website: "Learn the art of controlling minds..." After obtaining the manual, I mastered the techniques of hypnotic seduction. And now, I've made up my mind—to bring that woman completely under my control.
