Ya' think?
Seriously though, hell of a thing to be in a situation where the girl who blackmails you, encourages you to commit delinquency, and gets into fist fights with you is the only one that seems interested in knowing the real you rather than the role you've been inhabiting. Would have been bad enough without the nice-girl yandere best friend.
The bit after waking up and Kokoro was there... that's full on horror.
