Useless is way overstating it. Being less socially competent is fine, it's that age after all. Remember, Miku was less socially competent as a kid too, and Yukiya helped her overcome it. Way worse at cooking? I would be surprised if a boy cooks better than a girl (that's taught by her gran). At least he can chop veggies well enough. And finally, we can also see that he beats her at gaming as well, not simply one-way, so this is just cherry picking.
Our homeboy is a virgin, but he isn't useless nor pathetic. He's reliable, caring, and attentive, and he actually puts in the effort to be a better version of himself. Plus, being a social butterfly is hardly a one-up in any regard.
The only character in my book that's a true pathetic virgin is Kazuya Kinoshita from You-Know-Which-Series. Pure hundreds of chapters of garbage, that shit can't even compare to 10 chapters of this manga.
