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...
Besides, she says to k-k-k-kiss like 
it's so easy, but it's my first time!
Sie redet vom K-K-K-Küssen
als wäre es ein Kinderspiel,
Además, lo dice como si nada,
pero ¡es mi primera vez!
Además, lo dice como si nada,
pero ¡es mi primera vez!
À l’entendre, ça a l’air facile,
mais moi, c’est mon premier baiser !
E poi, ha detto di b-b-b-baciarla come se
fosse facile, ma è la mia prima volta!
Além disso, ela diz b-b-beijo assim
 fácil, mas é a minha primeira vez!
К тому же, п-п-п-поцеловаться?! 
Я же ни разу этого не делал!
