Ever since childhood, Haruka Kotoura's classmates have viewed her as a creepy and monstrous individual. This stems from her ability to read other people's minds—the very same ability that drove her parents away, leaving her alone with her grandfather. Consequently, she has grown accustomed to the bitter treatment from those around her, becoming completely cold and unsociable toward others. However, everything begins to change when Haruka transfers to a new school. While most people are put off by her as usual, she meets Yoshihisa Manabe, who finds her power astonishing. Yoshihisa then proceeds to befriend Haruka, promising to never leave her no matter what happens. Haruka's new experiences of social belonging thus begin, as she meets new friends and learns to open herself along the way.
