Basically this is gonna be a rant about the leading male character. You have been warned.
He almost has no emotions. His motives aren't explained at all. For example, why does he take care of her at the start? They weren't really friends before that. The became friends afterwards. Because her apartment is too messy and she doesn't eat healthy food? So what? I bet a lot of people live like that. Is he gonna help out every random person he meets?
Why does he put up with her awful personality? Again they weren't friends. We never see him showing any signs of falling for her or anything so that crap about loving her for who she really is, is bull. If he had a crush on her or something so he did all that but she wasn't aware of that *friendzone* that'd be far better than what we got.
He doesn't know what he wants. He switches from one girl to another real quick. And of course the 3 main female characters in the show fall for him. OK, Taiga falling for him is understandable. Minori suddenly can't stand his charms? Ah, well, we'll let it slide. But why did they have to make the model fall for him too? It's like they know he's the main character so they have to fall for him. It would've been excused if he was particularly handsome or charming but he isn't. So why do they all fall for him?
