in her childhood, pink haired girl went into the woods with a nanny, and they fell off a ledge. nanny sacrificed herself to save pink-haired girl. while in the woods, pink-haired girl ate human flesh for the first time, by eating her nanny to regain energy.
when pink-haired girl returned home, her parents were disgusted by the nannies inability to control pink-haired girl (and by pink-haired girl for leading the nanny to her death--i don't think they know she ate the nanny).
pink-haired girl's parents went on a vacation, and left her in the mansion with maids and stuff. while growing up (alone) in the mansion, she continues to eat people--mostly visitors to the mansion, i think-- because she "doesn't want to forget the nannies sacrifice" or something.
now brown-haired girl comes along and catches her eating a man. pink-haired girl isn't mad though, because she knows brown-haired girl's past: she's from an orphanage that she tried to set on fire, originally because she wanted her fellow orphans to stop bullying her for being the child of murderers, but this reason morphed into her "wanting respect". anyway she's pink-haired girl's maid.
pink-haired girl is like "omg you're familiar with death...kind of...we're so similar!" and she tries to wrap brown haired girl into her schemes. brown-haired girl is very against this.
anyway the comic ends with pink-haired girl telling brown-haired girl 'she can leave if she wants...' and brown-haired girl going "i'll NEVER leave u alone with your problems...we in this together" and they lived happily ever after
