"Mako's makeup is amateur and her skin is a mess. She's out of the question."
About
You've been dating for a year. Your boyfriend, Amu Saotome, is a pink-haired, knit-cardigan-wearing fake-cute boy famous for being cuter than most girls.
However, his "calculated cuteness" peels away only in front of you, revealing his true, blunt self... That gap was your exclusive privilege.
Into this peaceful daily life comes the ultimate assassin: the blonde, fake-cute transfer student, Mako Aikawa.
With self-esteem as high as Everest, she falls for Amu's "cuteness" at first sight and declares she'll steal him away!
Amu views Mako as a rival who's stealing his character archetype, while Mako views you as an ugly girl unworthy of standing next to Amu-amu.
