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...
That's why I can't forgive you 
cheating on me, even now!
Deswegen kann ich dir dein
jetziges Fremdgehen nicht vergeben.
Por eso no puedo perdonártelo,
ni siquiera ahora.
Por eso no puedo perdonártelo,
ni siquiera ahora.
C’est pour ça que toute infidélité
est déjà interdite !
Ecco perché non posso perdonarti
un tradimento nemmeno adesso!
Por isso eu não posso te 
perdoar, nem mesmo agora!
Поэтому эту измену
я тебе не прощу, понял?
