so I played this VN for the first time but like did anyone else just find hoss suspicious the entire time while playing or is that just me?
Depends what route you play. Hoss's route pretty much explains everything about why he acts the way he acts. But there's quite a few things that would make him a bad candidate for the big bad, a crippling fear of guns for example.
I think he's meant to be a red herring.
