The good news is: Everybody being supportive knocks down one barrier enforcing heteronormativity...
I still suspect Hino's going to keep up the tease-but-not-actually-follow-through tactic until Koguma finally snaps and mauls her. (Maul as in flying glomp and make out with her.)
Who knows? Maybe the inevitable "How did it feel?" questions will nudge Koguma a little further along... because I know this manga ain't ending before I die.
