Two words. Fumino wins.
No, this isn't a spoiler; this is common sense.
The male character does seem a lot more together than many harem protagonists out there. Going from the first chapter alone he's not shy about who he cares about, nor particularly dense. This means that if they're going to have a convincing harem with plausible "competition," the "romance" with the other girls has to be really good.
Of course, I'm not holding my breath either. Harems have a way of failing that is unique to their particular species. And this one looks like it'll eventually be bigger than three (going by the covers of the light novel), which generally translates to less attention to individual characters [see To-LOVE-Ru for an egregious example].
