I'm amazed by the subtle (or not THAT subtle) contrast between the girl with pink hair and the dark-eyed one. The pink-haired girl has clearly seen and done some shit before, while the other seems more... naive, or pure. Is the pink girl being a bad influence on the dark eyed girl? Is this pink girl more f'd up than the other? The dark eyed girl is clearly more innocent, seemingly forgiving her friend in the end. And yet... the ending.
