So far we have an oblivious girl and a spineless guy who somehow got a degree in computer science, and somehow managed to live through middle school, high-school and university without learning what an otaku is - when his crush is one - and absolutely nothing about her hobbies when he's been interacting with her for about the same amount of time...

Then it's official: this protagonist is heavily autistic. And I mean legit autistic, the only thing he's missing are the repetitive movements.
