I love how she's not like "wow, this cute senpai is so sad, let me help her out" but is instead awoken to her sadistic tendencies and just wants to mess with her. XD
Damn, nice. Ch14 could have been an amazing intro chapter to this series... I wonder, are these chapters new, or has the translation just lagged behind? If they are new, it'd seem to me like the author has improved a lot as a storyteller.
