Yamada Ryu, a second year student who attends the prestigious Suzaku Private High School, is a problem child who comes to school late and leaves early, is prone to fighting all over the place, and even nods off in class. One day, he falls down the stairs with the honor student Shiraishi Urara. They faint, and when he wakes up in the infirmary he's turned into her!
I never promised to go on 
a date with you to begin with.
Wir waren ohnehin nie
miteinander verabredet.
Shiraishi-san tampoco prometió 
tener una cita conmigo.
Shiraishi-san tampoco prometió 
tener una cita conmigo.
En fait,
Non mi hai mai promesso di uscire insieme.
Eu nunca tinha te feito prometer
 sair comigo nem nada assim.
И я никогда не обещал,
что схожу на свидание с Сираиси.
