Gonna give my predictions for this arc
"Tiger's Den"
She's gonna get hit on by literally every dude, or maybe this one powerful guy with a lot of influence, or meets that one model guy from before who takes her aside for a while
and Kazuya wimps out or something because he's so self conscious.
I want to say he'll man up somehow by the end, but in all honesty he's probably just gonna grab her hand and run off to avoid confrontation
but fine, if there will be any progress, he's gonna try and stand up for himself and her somehow (very meekly)
