Whaaaat a guy and a girl in a shounen manga have a close relationship but don't get together romantically? Hell yeah, 10/10, A+. Too bad it ended so abruptly though... like what's up with that? I can't imagine it got axed when it was actually like. Good.
Edit: Ah, Gangan Online, that explains why it isn't really Shounen. Doesn't explain the axing though. If anything, that feels like it creates more questions...
