Embarrassed enough to not just nonchalantly go to a girl's house. Brazen enough to just slap a rude, bare ass out in public in the heat of the moment.
I'm certain many of us would share this sentiment.
Remember what Mana said a good few chapters ago? How it must be nice for things to fix themselves by doing nothing?
Here's to hoping that we don't get that with Nakano letting the opportunity pass by her yet again.
It's so odd that the narrator says their hearts were broken when both he and the girl he's going out with don't really care about one another. I really hope these two don't overreact to the weird experimental relationship Sensei's going to reveal to them, but I'm sure they will.
Hopefully Asahide can think rationally about all this.
Even if she did kill her mom, this isn't the place to just randomly stab someone, especially with the police on their way. This kinda thing'll haunt him for the rest of his life.
