A campus love battle between a calculating girl and a natural boy to see who will fall first! A guy with a pretty face, smart brains, attentive, and sensible, he's the perfect catch! Rio, a girl who doesn't miss, has her eye on Kawakita-kun, an innocent but strong-willed opponent...! (Source: Sho-Comi, translated)
