Brutally Mistaken

Every school day Chloette would sit at the same table with the same group of boys, laughing and joking together while they ate their lunch like they usually did.
Until one day a new boy joined the boisterous group: Tamaki Mizuko. Originally from Japan, he had moved to a small town in America for reasons his family would never admit; Tamaki was a yandere.
Unfortunately, he had not yet gotten over his late obsession, Saki, who was now far out of his reach in his old homeland.
Chloette decided to help him control his obsessive behaviour.
But what will happen when his object of desire is no longer desirable...

... And his new obsession becomes the very person trying to cure him?

She thought he was improving.
Chloette could never have known just how brutally mistaken she was.
