Ako Kobayashi is a high school girl eagerly awaiting her prince charming to sweep her off her feet, but she has to overcome one small problem: she is so afraid of guys that she breaks out in hives whenever she comes near one. She even rejects the popular Kei Kitaooji who is the first guy to ever ask her out. However, after Kei learns of Ako's condition, he comes to school the next day dressed as a girl and asks her out again.
