Totally unrelated, but I just read
Mukuchi na Bakemono wa Yoru ni Naku tonight. It reminded me of this a lot(that's not to say they are the same, mind you), with the whole "main char getting avoided" theme. It's only a 46 page one-shot, and I know I'm just posting this initially on me being hyped or whatever, but i'd say check it out. It's too bad that it was only a one-shot
