Kouhai-kun is the silent and genius type of guy. He never really speaks in class or takes part in any activities. He always studies and even scares the teachers because of his arrogant genius attitude.
Then he meets the new transferred girl, Hijiki, at the entrance of school, who he found some sort of interest in since he discovered that she is lying. After a short time, he opens himself up a little, but will he respond to Hijiki's feelings?
