We never learn
Résumé
Nariyuki Yuiga comes from an impoverished family, so he’s eager to secure a full scholarship to college when he graduates high school. His principal agrees, with one stipulation—he must tutor the two smartest girls at the school and make sure they get into their target colleges! Rizu is a science genius who wants to study liberal arts. Fumino is effortlessly good at literature, but math makes her head spin. Nariyuki is stuck between a rock and a hard place, but who can complain about tutoring a couple of cute girls?
