Matsura is a calm, composed high school boy who's always lived his life putting up a front. He’s good at reading people and can easily see through them to their true nature, but for unknown reasons, he's constantly approached by Kyuuragi — a beautiful girl with twin tails who is part of the popular group! Whether it's intentional or not, her playful and cunning actions keep throwing him off, and before he knows it, Matsura is yelling, "Stop! I'm falling for you!"
