It's hilarious how unnatural and stupid the hatred for the mc is. Everyone hates him because some girl talks to him a bit and perhaps likes him? Get over yourselves, that's just pathetic. In the real world, stuff like that is truly way too rare because people couldn't care less. Why are they acting as if he's NTR-ing their asses?
Also, amanogawa kouki always makes me laugh, he was ridiculous in the novel, ridiculously stupid that is. I wonder if he's as much of a deluded moron here in the manga?
Well, he pretty much proved himself to be in this chapter, he actually claims the mc is fawning over that girl, I think he's not only retarded, he's also blind.
