@evilpeach She didn't take a swing with her bag, in earlier panels you can see that she notices a piece of wood , and in others you can subtly see her holding it. (In the panel of the fella going ! before she says hello, and when he charges at her before the lights go out)
That piece of wood not gonna drop a man there is no weight behind it...on other hand, if she find almost head size rock put it in the bag and swing it at full force that will do.
I hope the new guy is handsome, i hope he is kind to our Yoshino, i hope he like Yoshino, i hope he is th second male lead, and i hope he is Kirishima Rival hahahha. I want to see Kirishima suffer from jealous 🤦♀.
