The story of two girls who have been together in all things since they were children. Yukari has always been the type who wanted to do everything her best friend Haru did. It's unclear whether she acts out of envy, love, or madness, but her feelings become a darkness that leads to a tragic fate...
I didn't mean that... I'm just 
worried about your future!
!لم أقصد ذلك... إنّما أنا قلقة بشأن مستقبلك
So meinte ich das nicht … Ich mach
mir nur Sorgen um deine Zukunft.
Non era mia intenzione...
Sono solo preoccupata per il tuo futuro!
Não quis ser insensível... 
Só me preocupo com o seu futuro!
