See it makes sense to me Hyoudou is so insistent here- if this crazy world is real, so was that! He's a stubborn old man, and talking to his rival, too. So he digs his feet in on Fuck You I Know What I'm Talking About...
...or am I filling in on the authors behalf? Probably lmfao. But I don't mind. Some authors I'm willing to skate past a lot.
Otherwise, I really find the two leads charming this chapter. Their old-man bluntness and sense of care is great.
