I suppose the plot requires it, but I still find it annoying how indecisive, vague, and gloomy the MC dude is. I'm not referring to his objection to dating Mio, or anything like that, since that's the core plot element of the story, but everything else about him. The series is perfectly aware of it, naturally, with Makio noting Iori doesn't feel like a guy. Not saying all guys automatically would be decisive, focused, and steady, but I suppose it works as a sort of stereotypic ideal reference. Iori's traits combine to make him a doormat kind of personality, which is near the top of my dislike list, only losing to blistering idiots. He's not the worst of his kind, but this isn't exactly an action series, so much of the negative traits are hidden without the mortal danger looming around.
