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...
By the way, if one's name 
remains unpaired for 24 hours,
Übrigens, falls jemand
für 24 Stunden ungepaart bleibt,
Por cierto, si dejas un nombre
solo durante 24 horas,
Y si dejas un nombre
sin pareja 24 horas,
Et si tu ne fais rien durant ces 24 h,
tu resteras puceau toute ta vie,
Tra l'altro, se non si aggiunge
un altro nome entro 24 ore,
Aliás, se um nome ficar
 sem par por 24 horas,
И если не найти тебе пару за сутки,
 будешь девственником всю жизнь...
