It doesn't really have a direction. Even in SoL manga, most tend to have a vague sense of direction. Even if a manga is just 'kids playing together and having fun', it still tends to have a goal of 'having fun'. This manga has the MC just existing. And while that's fine, and the story is still fun to read, it leave a sense of emptiness.
the only way I know this has any sort of linear progression in time is because the month is mentioned at the start of the chapter and it keeps being a different month on the calendar.
Everything else about this is very vignette-centric - down to the fact that, while the ML clearly feels some sort of way about the FL, and you could make a (I think still somewhat thin) argument that she sees him as anything more than an entertaining distraction before she has to go to her sport club after school, there's really no velocity to their overall relationship, because he wants to hang out with his dominoes, and she's the one that comes barging in and brings all the energy to each chapter.
Which, I think is fine, honestly, because it defies a lot of the expected conventions of school-age comedy manga. Leaving out the (for now) explicit "rom-" part of that genre label is a clear departure from
so many titles of manga out there, that it feels incomplete to not have it here when it's a boy and girl lead set in a high school.
The boy is even a thoughtful introvert and the girl's a pushy sporty extrovert; two archetypes that are almost omnipresent in romcom manga.
So seeing them interact in a way that could be argued as not-actually/not-quite flirting, on top of the majority of each chapter taking place in a single room with no continuation of events between chapters to represent a clear progression of plot, is where I think that "missing something" sensation comes from, if I'm honest.
This chapter is probably the most overt so far in seeing the ML wish to do things beyond just his dominoes, and I personally am kinda sad about it because I'd hoped this would remain that "clear departure" story that I've mentioned before:
The ML just vibes in his club room alone, playing with dominoes; sometimes a friend shows up, tries to pull him somewhere, and he refuses; then the FL shows up, proposes some wacky scenario, she and the ML banter a bit and he has a comeback for every comment/remark she throws out, and then she leaves for club and he reminisces on how their interaction poses as some metaphor for life/youth/existence/what-have-you ... all without actual romance developing, but rather a strange/interesting/fulfilling friendship that exists solely within the confines of his little walled-in world.
I fully doubt that will happen, of course. But, it'd be neat to see this story buck convention, conceptually, using these characters and this setup.
