Gaaaay! I'm so happy Akari is so willing to accept that she does have feelings for Jirou. And that you don't have to waste time on chapters of her wondering if she does/doesn't. She's always kind of liked him, but just had this infatuation with Minami.
What I absolutely hate is this Shiori crap! I get the obstacle she creates to the story, but it's unnecessary drama and wastes time that could be filled with some Jirou/Akari action. In any other story maybe I'd be rooting for Shiori, but not this one. They're both too spineless to realistically work as a couple anyway lol. Jirou needs that pushiness from Akari to act like an actual man lol. Am I wrong?
Prediction Jirou will start dating Shiori and it'll hurt Akari, somehow they'll end up making A rank to switch. Jirou will switch to Shiori and then realize he wants Akari. I'd put money on it. It'll frustrate the hell out me, but will still probably be pretty good. I really do like this manga overall definitely better than the premise makes it out to be
