Nariyuki Yuiga comes from an impoverished family, so he's eager to secure a full scholarship to college before he graduates high school. His principal agrees, with one stipulation--he must tutor three of the most talented girls at school and make sure they get into their target colleges!

Rizu Ogata's a genius when it comes to science and math, but she can't seem to understand the subtleties of human emotion.

At the same time, Rizu's dealing with self-esteem issues, and because of her conflicted feelings, she suddenly disappears!
