Wait does this mean he WOULD jump at Miyahara if he knew she liked him romantically?
Also, I agree I see the inconclusive ending looming, which absolutely sucks. To be fair, they're like in early middle school, so it's still quite early for them.

So yeah, I can see why they are still immature and that they won't be dating by the end.
