Of course he isn't normal... bullying someone is already a flag that the bully has issues, but with how horrid and inhumane his bullying was towards nagare, I'd pity any therapist who would have to talk to him, and he deserves to be just chaired at this point. But its exactly because he's so off the charts that something like jealousy/romance wouldn't really mesh well with something like him and he would have a twisted perception towards it
Seems like okaya jealous of yuda (and for several reasons too) so he bullied him... which of course resulted in nagare stepping in to save him, pissing him off even more, and the rest is history huh
