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 anyone is going to become your lover, 
Akane-senpai, it should be me!
Pero si alguien debe ser tu amante,
¡esa debería ser yo!
Pero si alguien debe ser tu amante,
¡esa debería ser yo!
Mais si tu dois sortir avec quelqu’un,
ça devrait être avec moi !
Ma se qualcuno farà coppia con te... 
dovrei essere io, Akane-senpai!
Mas, se ele pode ser seu 
namorado, eu também posso!
Но если кто-то и должен быть 
с тобой парой, Аканэ, то это я!
