Yandere Sim fanfic

A yandere girl finally finds colour in her grey world but her true emotions are coming out after a long slumber...
Stunned by the personality, she tries to stop herself from becoming the heartless, love-devoted monster she was born to be; will she be able to prevent herself from a massacre or will she have to become one with her insane self?
Sorry if that sounded weird but I'll try my best to make the story better..
The characters do not belong to me unless I decide to add OCs...
