This is just some highschool shit, why everyone is so fucking pretentious or vague with their answers. I've gone from getting pissed to just laugh at how overblown every little thing is in this story.
Plus the only decent girl/guy is Totsuka. Hachiman should make a move soon.
I agree with Hayama, you don't just randomly ask that when you're not even friends and barely talk. If he doesn't want to tell then leave him be. Just because Hayama's friend asked them to find out, it's plaon rude to stick your nose like that.
