You've been dating for a year. Your boyfriend, Amu Saotome, with his pink hair and knit cardigan, is a burikko boy rumored to be cuter than any girl.
However, his "cutesy" act only drops when he's with you, revealing his true blunt self... That gap is your special privilege.
Into this peaceful daily life comes the ultimate assassin: A blonde burikko transfer student, Mako Aikawa.
With self-esteem as high as Mt. Everest, she falls for Amu's "cuteness" at first sight and declares she will steal him away!
Amu views Mako as a rival for his character archetype, while Mako views you as a plain girl who doesn't deserve to be next to Amu-Amu.
