(Average+) Loving Yamada at Lv999!

Series in one sentence:
Autistic introvert meets autistic extrovert.

Series in more sentences:
Akane joins an online multiplayer game for her boyfriend, but is dumped by him for another girl.
After having spent so much time and money on it, Akane keeps playing and begins to connect with her guild members more than she ever has, one of them being Yamada, an oddly stoic pro gamer who happens to live close-by.

A slow series wherein little happens.

The two main characters were too easily charmed by each other. They hardly interact -also thanks to the distant Yamada- yet whenever they see each other for a few seconds, one of them always seemingly does or says something pretty normal and it somehow makes the other woozy.
Why does Yamada, who literally doesn't care about anything, care?

I'm also surprised by how their blond friend took on this role of matchmaker, opposed to rival. I wasn't expecting it by the way he looked at Akane at times. I think the story would've been better if he pursued her.
His little sister was also rather quick at supporting her and Yamada as a couple, while she was seething of jealousy just an episode before.

I liked the voice actor for Akane, she has a pleasant voice and a very comedic delivery, even when nothing really funny is said. I also like lifeless autists like Yamada, but again, I didn't think his crush on her developed realistically.
The anime insists he's handsome and has female pursuers, so it's not like he's charmed by the experience that is positive female attention. He's already familiar. So, what does Akane bring to the table? That she's nice and pretty? Surely, he's met girls who are nice and pretty. None of the girls that approached him in the show seemed anything but.

I suppose it's her bubbliness and assertiveness that's supposed to make a difference, if I understood the blond friend correctly, but that basically means Yamada has to be forced into a relationship for him to want to get to know somebody. I'm not sure if that's healthy.
Granted, the anime doesn't make it weird, but it didn't give me a good reason for their attraction, either. We arrive at episode 11, and Akane admits not to know her crush. You are absolutely right, so then, tell me, why are you in love with him?

In the end, I was left unimpressed. Don't even know what the "level 999" in the anime's title is referring to.
