Yui, the childhood friend who loves Guest, and Riko, the girl with psychic powers.
About
Yui Minase and Guest, who have been together since elementary school, have entered the same high school. In middle school, they were teased by those around them for being so close that they must be a couple. In high school, Yui continues to ignore personal boundaries and fuss over him, and everyone expects the same old dynamic to continue—or so it seemed. However, from the corner of the classroom, a pair of grey eyes watched the scene coldly. Riko Nomura, a rational and quiet girl who wears her uniform perfectly. Possessing a world of her own where no one else is allowed to move, she would never permit their sweet daily life to continue.
