They say great minds think alike.

But when two of the smartest students in school, Cho Kyuhyun and Jung Raeha are paired up for a series of intense contests, they have to be constantly reminded that they're supposed to compete against the other schools— not against each other.

Jung Raeha is free-spirited, careless, and easily distracted. She solves problems through creativity and ingenuity. She never studies, but gets the best grades in the class. She helps her classmates with anything (especially tutoring), because she's a pushover. She always complains that Cho Kyuhyun is too uptight and should learn to loosen up.

Cho Kyuhyun is focused and hard-working. He is driven to succeed, works extremely hard, and studies pretty much all the time, making him a favorite for teachers; so he always gets frustrated when Raeha beats him in practically everything. He never socializes because he claims it's "a waste of time" that could be better spent doing something productive. He's a stickler for the rules, and does everything by the book. For him, there is no "other way" than the ways that have been done already and have been proven right. He believes that Raeha is too free-spirited for her own good and doesn't take things seriously enough.

What happens when two geniuses with conflicting philiosphies heads??
