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...
A human and an angel being paired together

Una pareja de humano y ángel
no es algo corriente,
Un couple avec un humain
et un ange est assez rare,

umani e angeli facciano coppia,
Não é comum um humano e
 um anjo formarem um casal,
Любовная связь между ангелом
и человеком — редкое явление,
