Today's chapter went a little too far with the suspension of disbelief. Now we know our MC is pretty much like the rest, a puritan monk under shonen guidelines.
I'm actually enjoying how indecisive the MC is being right now, it keeps it refreshing and allows the other girls besides Kanai to show how they love and appreciate him. I wouldn't be mad if this goes on for a bit, I hope boundaries are set with Himenono cuz as much as I love her, I don't want her to cougar the MC
