This is a bit hackneyed, but.... so leeeeewd.....
I know Koguma is canonically oblivious about anything involving Hino, but she hardly resisted at all before letting her /lick and kiss her neck/. And (apparently) got visibly hot under the collar (yeah, let's call it that). What will it take for her to a) realise Hino has it baaad for her, and b) that she (Koguma) is totally down with that idea?
Not that I mind being along for the ride, of course....
