Aino Seiji is your typical male high school student when he meets Guri, who is a shinigami? No, a pervert--no! An angel?! Guri introduces him to the Kiss Note and explains that if he doesn't kiss someone within 24 hours, she will die. So it's off to Seiji's school to find his school crush, his classmate, Hiyama Akane, but of course nothing is ever so simple...
But if she returns your feelings,
then that's great, right?
Aber ist doch toll, wenn Gefühle
auf Gegenseitigkeit beruhen.
Pero si acepta tus sentimientos
estará bien, ¿no?
Pero si acepta 
tus sentimientos todo irá bien.
Mais elle en pince pour toi,
tant mieux, non ?
Ma se ricambia i tuoi sentimenti
è una bella cosa, no?
Mas não é melhor que ela
 também goste de você?
