God I really hope this picks up soon. It’s normal to spend the first few chapters establishing a baseline, but we’re getting to the point to where we need to start seeing SOME kind of progress. Even something as simple as showing that Sayaka also likes MC would be enough
I just really like the FMC design and I want to see something happen before Axe-kun walks into the room
we have gotten some.
It's hinted at and not outright stated, but it would appear that Kazuki was beaten out in some tournament or competition by Sayaka back in middle school, and it shocked him to the point that he quit the dojo completely, and fell into video games to the point of it seemingly taking over his life.
He had always been "the leader" and the person Sayaka apparently depended on for everything when they were children. So when she suddenly succeeded him, it was a blow to his ego. And while not (yet) confirmed, it was a big enough blow to his ego that he quit in a tantrum-like way, and has since lost all interest in all of the things he was doing--school, social life with peers, going outside. He now stays up all night playing games, sleeps through class, sits around at home and has to be harassed and threatened into helping out with chores, and he is rather sullen toward Sayaka in most ways whenever interacting with her.
In contrast--Sayaka has continued excelling, becoming a top-grade student, outstanding athlete, and has friends where she was mostly hiding in Kazuki's shadow when they were younger, always trailing after him and appearing much more meek. So she's "blossomed", while he turned inward and sank.
However - we see that he's also now realizing Sayaka's a hot teenage girl, and his hormones are now fighting with his desire to keep to his sedintary and avoidant lifestyle. But despite his intentional lashing out and harsh tone toward her, he still covers for her and almost reflexively looks out for her, because she's still one of his oldest and closest friends.
So 8 chapters in, the blanks of his backstory and the foundation for his current characterization are being laid out and shown to us. That means we know the reason behind his being at rock bottom, and the next step is figuring out reasons that will compel him to
want to improve his lot in life. Sayaka will almost assuredly factor into that in some fashion, and it'll dovetail with her own arc, as we (hopefully) learn more about her specific perspective of things.
Because as of right now, we're getting Kazuki's story. The extent that I think we can say about Sayaka, is that she remains very attached to Kazuki, and she's behaving largely in the same manner she did before--to the point that it's seemingly incongruent, because she's clingy and physically close to him, only she means nothing "intimate" or romantic by it. Kazuki's stuck interpreting it that way, or at least actively trying to resist doing so, which is where his flustered behavior factors in.
I'm not personally a fan of people like Kazuki, mind--though as a
character, he's set up kinda nicely, if the author's intent is to have him grow past this sullen sulky teenager phase where he ran away from something in middle school, and has to find his way back to engaging with Life again. I hope the author has big plans for Kazuki to turn things around for himself, because the bones for a halfway decent "growing up" story are already there.
If he just stays this way, or doesn't meaningfully engage with his past and doesn't grow through it and mature and
still "gets the girl", I'll be disappointed. But it's way too early to make that call, at this juncture, and we're already getting details that infer intent for him as the narrative progresses.
